As recently discussed on lwn.net: https://lwn.net/Articles/695478/
The kernel has special behaviour for uid/gid 65534:
1. The kernel maps UIDs > 65535 to it when some subsystem/API/fs
only supports 16bit UIDs, but a 32bit UID is passed to it.
2. it's used by the kernel's user namespacing as the internal UID
that external UIDs are mapped to that don't have any local mapping.
3. It's used by NFS for all user IDs that cannot be mapped locally if
UID mapping is enabled.
Most distributions already map (or are in the progress of changing)
nobody/nogroup to the 65534 uid/gid, so lets do so as well.

Currently, our /etc/mtab points to /proc/mounts. This was all neat so
far, and was good for a sysv-like init system.
However, the way today is to point it at /proc/self/mounts, the
per-process mount tab.
Additionnally, that's what systemd expects. If /etc/mtab is not a
symlink to ../proc/self/mounts and the rootfs is readonly, systemd would
whine loudly (and a service unit would be marked failed).
Since it works well for sysv-like init systems too, just use that.

The ldconfig handling in the main Makefile is utterly broken, as it
calls the build machine ldconfig to generate the ld.so.cache of the
target. Unfortunately, the format of the ld.so.cache is architecture
specific, and therefore the build machine ldconfig cannot be used
as-is.
This patch therefore simply drops using ldconfig entirely, and removes
/etc/ld.so.conf.d/ from the target skeleton. The idea is that all
libraries that should be loaded by the dynamic linker must be
installed in paths where the dynamic linker searches them by default
(typically /lib or /usr/lib).
This might potentially break a few packages, but the only way to know
is to actually stop handling ldconfig.
In order to be notified of such cases, we add a check in
target-finalize to verify that there is no /etc/ld.so.conf file as
well as no /etc/ld.so.conf.d directory.

This patch has same purpose than 49964858f4:
On some machines, the network interface is slow to appear. For example,
on the Raspberry Pi, the network interface eth0 is an ethernet-over-USB,
and our standard boot process is too fast, so our network startup script
is called before the USB bus is compeltely enumerated, thus it can't
configure eth0.
Closes#8116.
However, wait-delay hook is enabled only if wait-delay property appears
in /etc/network/interfaces. This patch enable it automaticaly when
interface is configured through DHCP at bootup. But, if user choose
to write /etc/network/interface himself, he have to explicitly

systemd is increasingly expecting things to live in /usr/bin, /usr/sbin
or /usr/lib nad not in /bin, /sbin or /lib. It has inherited those
expectations from a Fedora change:
https://fedoraproject.org/wiki/Features/UsrMove
Note however, that systemd does support /usr being on a separate
filesystem; it just expects an initramfs to mount it before the final
switchroot over to the actual rootfs.
But the traditional use-case for Buildroot is not to boot with an
initramfs; although that is totally feasible, that's probably not what
is commonly done in the vast majority of cases.
However, a lot of packages still install stuff directly into /bin,
/sbin or /lib, which systemd may need early-on in the boot process,
even before it may have a chance to mount /usr. Even though we can
tell systemd, at configure-time, where it should expect programs to
be at runtime, it does not make sense to go head-first against an
upstream wa^Hill.
Add an option so that /bin, /sbin and /lib be symlinks to /usr/bin
and /usr/sbin. That option is forcibly enabled when the init system
is systemd.
Note: we need not handle /lib32 or /lib64, as they already are symlinks
to /lib, which means they will automatically be redirected to /usr/lib,
as /usr/lib32 and /usr/lib64 already are.
Furthermore, this means we're no longer supporting a split-usr setup, so
the corresponding configure options have been removed as well for
systemd and, when using a merged /usr, for eudev as well.
In Buildroot, we decided (with this patch) not to support a split-usr
when systemd is used as an init system. This is a design decision, not
a systemd issue. Thus the select is with BR2_INIT_SYSTEMD rather than
with BR2_PACKAGE_SYSTEMD.

/dev/shm is needed for systems using shared memory. On init-based systems
this directory is usually created in the inittab along with /dev/pts, by
the lines:
package/busybox/inittab:
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
package/sysvinit/inittab:
si2::sysinit:/bin/mkdir -p /dev/pts
si3::sysinit:/bin/mkdir -p /dev/shm
However this is broken when static /dev management is selected and the root
filesystem is read-only, showing during boot the error:
mkdir: can't create directory '/dev/shm': Read-only file system
Fix it by creating the empty /dev/shm directory, just like /dev/pts.

Making /var/run and /run symlinks to /tmp is bad since the underlying
tmpfs filesystem is mode 1777 which leads to possible security attack
vectors via badly owned/mask-mode pidfiles and state files residing there.
So make /run a proper directory with /var/run symlinked to it.
Eventually all startup scripts and state info should be pointed to /run
directly as per the linux fhs and good practice.
Add a tmpfs filesystem entry for /run so that busybox inittab, systemv
inittab and systemd automount mounts it there to avoid breaking the
system.
While at it fix inconsistent spacing in /etc/fstab by using tabs and

Instead update the sed expressions to match clean non-commented strings
by searching for "-o remount,rw /" and checking that's the end of the
