sure. the user tools are in CVS for the moment :
but Daniel will probably release something soon. the lxc-checkpoint and
lxc-restart tools are a bit too optimistic on the availability of the
checkpoint and restart syscalls, a cleanup might be needed.
the patchset is here :
it's based on top of current mainline and includes :
. sysfs patches for net namespace
. freezer subsystem
. oren's V5 checkpoint and restart patches
. a personal hack to do external checkpoint and restart using
the lxc-checkpoint and lxc-restart tools
. some fixes
an old mq namespace implementation (being reworked currently)
restart is still bogus because some state is not well captured at
I'm working on it right now !
