The different tools and libraries in util-linux have a lot of optional
dependencies. When we want to support those optional dependencies, we
can easily generate dependency cycles. For instance, findmount and lsblk
need udev to work correctly, but eudev and systemd both depend libblkid,
which comes from util-linux.
Normal distros (e.g. Debian) solve this by first building a minimal
package that has no dependencies at all, then build the packages that
depend on util-linux, and finally rebuild util-linux with all bells and
whistles. Solve it in Buildroot by means of the following changes:
- Split util-linux into two packages:
- util-linux-libs, providing lib{blkid,fdisk,mount,smartcols,uuid}.
- util-linux, providing both the aforementioned libs and the programs.
- Add a blind selection for util-linux-libs, i.e. it is indirectly
selected according to the util-linux options.
- Make host and target util-linux have a build dependencies on the -libs
packages.
- Make eudev and systemd have build dependencies on util-linux-libs.
This can be extended to other packages in the future but is not needed
right now because the configuration options are backward-compatible.
- Make util-linux have an optional build dependency on the package that
provides libudev (either eudev or systemd), if it is selected.
Installing util-linux overrides files installed by util-linux-libs but
this is not a problem: it's allowed for a package to overwrite files
from another package, as long as there is a dependency between the two.
util-linux-libs has a Config.in symbol for the package as a whole, but
not for the individual libraries: it simply reuses the symbols of the
full package.
The build dependency of util-linux on util-linux-libs ensures that
util-linux overwrites the files installed by util-linux-libs and not
vice versa. In practice this dependency shouldn't be needed: the only
reason for util-linux-libs to be built is to break a circular
dependency. In that case, there is already a transitive dependency of
util-linux on util-linux-libs, so adding it explicitly is redundant.
Still, better safe than sorry.
host-util-linux-libs is not needed at the moment. It can be added if we
have a dependency cycle problem later.
With this approach we don't need to patch configuration files neither
change packages other than eudev and systemd.
Other packages that require util-linux libraries and whose libraries may
be used by util-linux programs can be updated later. We also don't need
to change any existing defconfig, since all configuration options are
kept in the util-linux package.

systemd is a system and service manager for Linux,
|
|
compatible with SysV and LSB init scripts. systemd provides
|
|
aggressive parallelization capabilities, uses socket and
|
|
D-Bus activation for starting services, offers on-demand
|
|
starting of daemons, keeps track of processes using Linux
|
|
cgroups, supports snapshotting and restoring of the system
|
|
state, maintains mount and automount points and implements
|
|
an elaborate transactional dependency-based service control
|
|
logic. It can work as a drop-in replacement for sysvinit.
|
|
|
|
Systemd requires a Linux kernel >= 3.0 with the following
|
|
options enabled:
|
|
|
|
- CONFIG_CGROUPS
|
|
- CONFIG_INOTIFY_USER
|
|
- CONFIG_FHANDLE
|
|
- CONFIG_AUTOFS4_FS
|
|
- CONFIG_TMPFS_POSIX_ACL
|
|
- CONFIG_TMPFS_XATTR
|
|
|
|
These options will be automatically enabled by Buildroot if
|
|
it is responsible for building the kernel. Otherwise, if you
|
|
are building your kernel outside of Buildroot, make sure
|
|
these options are enabled.
|
|
|
|
Systemd also provides udev, the userspace device daemon.
|
|
|
|
The selection of other packages will enable some features:
|
|
|
|
- acl package will add support for multi-seat.
|
|
- xz and/or l4 packages will add compression support in
|
|
journal and coredump.
|
|
- libcurl package will add support for systemd-journal-upload.
|
|
- libgcrypt package will add support for journal sealing and
|
|
DNSSEC verification in resolved.
|
|
|
|
Notice that systemd selects the fsck wrapper from util-linux
|
|
but no particular fsck.<fstype> is selected. You must choose
|
|
the apropriate ones (e.g. e2fsck, from the e2fsprogs
|
|
package) according to the system configuration.
