Using the GZIP environment variable to pass gzip options is
deprecated, and therefore we are going to remove the "GZIP = -n"

Since we use --xattrs-include='*' to include all extended attributes,
tar creates a PAX formatted archive. The archive metadata captures atime

is handled in fs/common.mk using touch on all files.

fakeroot by default forwards {f,l,}chown calls to libc and ignores
permission issues, which may cause issues when building in restricted
environments like user namespaces as set up with bubblewrap where a chown
call with a uid/gid not mapped in the user namespace instead returns EINVAL.
This error is not masked by fakeroot and returned to the caller, causing
failures.
There is no real reason to really perform the *chown calls in the context of
Buildroot (as the calls will likely just fail and files are not accessed
outside the fakeroot environment any way).
This forwarding can be disabled by setting the FAKEROOTDONTTRYCHOWN
environment variable, so set it when fakeroot is executed.

The static devices defined by packages are currently added to the full
device table when two conditions are met:
(1) ROOTFS_DEVICE_TABLES is non-empty
(2) BR2_ROOTFS_DEVICE_CREATION_STATIC=y
(2) is obviously correct. However, depending on (1) is not correct: if
the user doesn't provide any custom permission table and custom device
table, then ROOTFS_DEVICE_TABLES will be empty.
So instead, move the addition of the package-defined static devices
outside of condition (1), and have it only under condition (2).

In the current code, the creation of the main output directories
(BUILD_DIR, STAGING_DIR, HOST_DIR, TARGET_DIR, etc.) is done by a
global "dirs" target. While this works fine in the current situation,
it doesn't work well in a context where per-package host and target
directories are used.
For example, with the current code and per-package host directories,
the output/staging symbolic link ends up being created as a link to
the per-package package sysroot directory of the first package being
built, instead of the global sysroot.
This commit reworks the creation of those directories by having the
package/pkg-generic.mk code ensure that the build directory, target
directory, host directory, staging directory and binaries directory
exist before they are needed.
Two new targets, host-finalize and staging-finalize are added in the
main Makefile to create the compatibility symlinks for host and
staging directories. They will be extended later with additional logic
for per-package directories.
Thanks to those changes, the global "dirs" target is entirely removed.

By default, tar will not include any extended attribute (xattr) when
creating archives, and thus will not store capabilties either (as they
are stored in the xattr 'security.capability').
Using option --xattrs is enough to create a tarball with all the xattrs
attached to a file. However, extracting all xattrs from a tarball
requires that --xattrs-include='*' be used. This is not symetric (but on
purpose, as per the documentation), and so is confusing to some.
So, we use --xattrs-include='*' to create the archive, so as to be
explicit that we want all xattrs to be stored.

Since 118534fe54 (fs: use a common tarball as base for the other
filesystems), the filesystem creation is split in two steps, using an
intermediate tarball to carry the generic, common finalisations to the
per-filesystem finalisation and image creation.
However, this intermediate tarball causes an issue with capabilities:
they are entirely missing in the generated filesystems.
Capabilities are stored in the extended attribute security.capability,
which tar by default will not store/restore, unless explicitly told to,
e.g. with --xattrs-include='*', which we don't pass.
Now, passing this option when creating and extracting the intermediate
tarball, both done under fakeroot, will cause fakeroot to report an
invalid filetype for files with capabilities. mksquashfs would report
such unknown files as a warning, while mkfs.ext2 would fail (with a
similar error message), e.g.:
File [...]/usr/sbin/getcap has unrecognised filetype 0, ignoring
This is due to a poor interaction between tar and fakeroot; running as
root the exact same commands we run under fakeroot, works as expected.
Unfortunately, short of fixing fakeroot (which would first require
understanding the problem in there), we don't have much options.
The intermediate tarball was made to avoid redoing the same actions over
and over again for each filesystem to build. However, most of the time,
only one or two such filesystems would be enabled [0], and those actions
are usually pretty lightweight. So, using an intermediate tarball does
not provide a big optimisation.
The main reason to introduce the intermediate tarball, however, is that
it allows to postpone per-filesystem finalisations to be applied only
for the corresponding filesystem, not for all of them.
So, we get rid of the intermediate tarball, and simply move all of the
code to run under fakeroot to the per-filesystem fakeroot script.
Instead of extracting the intermediate tarball, we just rsync the
original target/ directory, and apply the filesystem finalisations on
that copy. The only thing still done in the rootfs-common step is to
generate the intermediate files (users file, devices file) that are used
in the fakeroot script.
Fixes: https://bugs.busybox.net/show_bug.cgi?id=11216
Note: an alternate solution would have been to keep the intermediate
tarball to keep most of the common finalisations, and move only the
permissions to each filesystem, but that was getting a bit more complex
and changed the ordering of permissions and post-fakeroot scripts. Once
we bite the bullet of having some common finalisation done in each
filesystem, it's easier to just move all of them.
[0] Most probsably, users would enable the real filesystem to put on
their device, plus the 'tar' filesystem, to be able to easily inspect
the content on their development machine.

Currently, the filesystems do not depend on building host-tar when it
is needed, even though all of them have to extract the intermediate
tarball.
However, in degenerate (but legally valid) configurations with no
user-selectable package selected, host-tar would not be built, so the
rootfs images would use whatever improper tar the system has.
Add the conditional dependency to host-tar to the rootfs-common
intermediate image. Since this is the internal step that all real rootfs
generators depend on, they now properly depend on host-tar when needed.
In practice, when host-tar is needed, it will always be built before the
rootfs images, because it is a dependency of all packages (except a very
few, like the skeleton), of which host-fakeroot, which is a mandatory
dependency of rootfs-comon anyway. But for consistency sake, let's
explicitly add host-tar as a dependency to rootfs-common too.
Note that rootfs-tar already had that dependency, and we leave it as-is
because it is semantically correct, even if superfluous.

Currently, when a custom user table and a package define the same user,
the settings from the package takes precedence over the ones from the
custom user table.
However, it makes sense to allow the settings from the custom user table
take precedence. For example, it would allow redirecting the user's
home directory to an alternate location (e.g. away from tmp and into a
partition that is persistent).
The support/scripts/mkusers script will only retain settings from the
latest definition it finds.
Thus, by passing the custom user table after the package defined users,
it is possible to override the package provided user definitions.

Each of the intermediate, per-rootfs target directories, as well as the

be the tweaks made by the filesystem image generations, but those tweaks

We normally do not remove intermediate files, but those can be quite

However, this means that, if any of the hooks or the image generation

We fix that by doing a copy of target/, run the hooks on that copy,
generate the generic tarball image out of that, and get rid of the copy.
This way, we can guarantee consistency of the target directory, and we

Currently, some filesystems may want to tweak the content of the target
directory, create special device nodes etc... This all means that:
- the content of the target directory for a specific filesystems may
depend on whether another filesystem is enabled or not; for example,
cpio will create a /init script or symlink and a /dev/console node;
- the filesystems can not be built in parallel, because they may change
the content of the target directory while another is being assembled.
Furthermore, the same fakeroot script is executed over-and-over-again
for each filesystem, to create the device nodes, the users and their
homes and files, and setting permissions...
We introduce an intermediate tarball, for which we do the full fakeroot
shebang.
That tarball then serves as the base for the other filesystems, with a
very simple fakeroot script that untars the common tarball, and calls
the actual filesystem image generator on that.
Note that we use a very simple tar command to generate the intermediate
tarball, because we are not concerned with reproducibility of the
archive itself (only of the archived files).

This will be useful in later patches, when we need more per-rootfs
variables, like a per-rootfs TARGET_DIR for example.
In Makefiles, per-rule variables trickle down the dependency chain, to
all dependencies of that rule, so we have to stop ROOTFS as soon as
we're not in a rootfs. This means we have to stop it at target-finalize
(which is a dependency of all filesystems), and for each package
individually, since some packages (host or target) can be direct
dependencies of filesystems as well.

Currently, when we build a cpio filesystem without static devices, we
shoehorn the /dev/console node as if it were specified by a package.
This means that this device is added for all filesystems as well, not
just the cpio. But if we disable cpio, that device is not created for
other filesystems.
This is not very clean, and may break expectations.
Instead, use an explicit mknod as part of the _CMD, as we know it's
going to run under fakeroot.
This is still visible to all filesystems built after cpio, and not to
those built before it, though.
