[lxc-devel] [PATCH] lxc-fedora template - systemd console gettys

[Serge Hallyn]

Quoting Michael H. Warfield (mhw at WittsEnd.com):
> Hey all...

> Patch to the lxc-fedora template to setup gettys on the ttys that are
> enabled in the configuration.  The area of the code already had some
> modifications to that service that didn't seem to do anything and would
> get wiped out by an update.  I commented that out but subsumed the
> change it was attempting into my command in case it does something on
> another rev somewhere.

> systemd.  This isn't unique to Fedora.  The templates for Fedora,
> ArchLinux, and OpenSuse are the only three that seem to have any
> reference to systemd at all.

Stupid systemd question - I assume based on this that the override copy
is /etc/somepath and the original is /lib/somepath?
