Another update to the lxc (Linux container) ocf file. (attached)
Changes (summary):
Added "very very very experimental" support for alternate init systems
inside containers (it should now support sysvinit, upstart and systemd).
Adding this support did not "break" the default sysvinit, but since I do
not know how to create a LXC container that uses 'upstart' or 'systemd'
my testing is very rudimentary for those two systems.
I have made no progress whatsoever with removing the requirement for
"screen" as I still have not found a working alternative to provide the
"root console" created by lxc-start (it takes over the default console
it's run on and that is lost when run as a cluster service, if screen is
not used.)
At this point I may have to confess that getting this working without
using screen may be beyond my abilities (for now, I'm stubborn so will
keep plugging away at this, but don't hold your breath).
I'm still not sure why the use of screen is so repellent to some, as it
works well and is quite innocuous generally.
Regards
Darren
