Bug#868159: systemd-setup-tmpfiles startup error when /srv is on read-only fs

[Alexander Barinov]

Package: systemd
Version: 233-10
Severity: normal

When / is placed on read-only fs and therefore /srv is read-only during startup
the following error occures:
localhost systemd-tmpfiles[570]: Unable to fix SELinux security
context of /srv: Read-only file system
I tried remounting / rw and executing 'restorecon /srv' but it didn't help -
systemd wants to change the context during startup anyway.
As this is not really an error and does not affect system functionality in any
way this should not be treated as error but as a warning.
