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

[Michael H. Warfield]

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.

This is very similar to the logic in the OpenSuse template but doesn't
seem to appear in other templates, such as arch, which have to deal with
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.

Attached below the jump.

Regards,
Mike
