Bug#1114953: systemd: fails to upgrade in chroot without /proc

[Christoph Anton Mitterer]

Package: systemd
Version: 258~rc4-1
Severity: normal


Hey.

Not sure if this is simply no longer supported, but upgrading
systemd now fails in a chroot, when /proc isn't bind mounted
into that:
Setting up systemd (258~rc4-1) ...
Cannot open '/etc/machine-id' in neither writable nor read-only mode: Function not implemented
dpkg: error processing package systemd (--configure):
 installed systemd package post-installation script subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of udev:
 udev depends on systemd | systemd-standalone-sysusers | systemd-sysusers; however:
  Package systemd is not configured yet.
  Package systemd-standalone-sysusers is not installed.
  Package systemd-sysusers is not installed.
  Package systemd which provides systemd-sysusers is not configured yet.
...


To the least the error is a bit misleading, as it even fails with the same,
if the file is set u+w.

Cheers,
Chris.
