[PATCH 3/4] base-files: Install /etc/mtab in a systemd-friendly way

[Jörg Sommer]

From: Jörg Sommer <joerg.sommer@navimatix.de>

The old mtab pointed to /proc/mounts which itself is a symlink. Systemd
therefore tries to replace it with a symlink to /proc/self/mounts, but fails
on a read-only rootfs:

    systemd-tmpfiles: symlink(../proc/self/mounts, /etc/mtab) failed: Read-only file system

This should be absolute /proc/self/mounts otherwise it's assuming
sysconfdir is only one directory level deep, and AFIACT, there is no reason
for it to be absolute

[PATCH 4/4] systemd: Ship /srv with the package

[Jörg Sommer]

From: Jörg Sommer <joerg.sommer@navimatix.de>

If *volatile-binds* gets removed from RDEPENDS, the /srv directory is not
part of the image, and tmpfiles tries to create it on boot, but fails on a
read-only rootfs:

systemd-tmpfiles: /srv does not exist and cannot be created as the file system is read-only.

Hi Jörg,

You probably also need to modify the FILES variable, as we get this
error on the autobuilder:

ERROR: systemd-1_259.5-r0 do_package: QA Issue: systemd: Files/directories were installed but not shipped in any package:
  /srv

https://autobuilder.yoctoproject.org/valkyrie/#/builders/9/builds/4061
https://autobuilder.yoctoproject.org/valkyrie/#/builders/10/builds/4078
https://autobuilder.yoctoproject.org/valkyrie/#/builders/20/builds/4041
https://autobuilder.yoctoproject.org/valkyrie/#/builders/22/builds/4105

Can you have a look at the issue?

Thanks,
Mathieu
