Comment # 26 on bug 1029129 from Franck Bui

Then your package will need to handle this SLE specificity. I'm not sure to
understand the prob, various packages need to handle SLE and Factory
differently for some parts even if Factory served as base for SLE.

That said I'm not sure we have to advertise these 2 variables in SLE. We could
still support them silently for SLE but users don't need to see them documented
in /etc/sysconfig.

@Thorsten, I asked you that already in JIRA, but don't you think we should drop
DISABLE_RESTART_ON_UPDATE too from /etc/sysconfig (and from yast2 too) so that
no one would be tempted to use them ?

Of course systemd rpm macros will still support DISABLE_RESTART_ON_UPDATE as we
already discussed.
