[Users] Checkpoint and restore on 64 bit Debian host.

[Matthew Franz]

I'm currently running several servers (for development environments)
on Debian Squeeze but am in the process of migrating to CentOS 6
because it seems to be a better supported environment and also
provides an LTS OS, whereas Debian's support lifecycle is more
"nuanced."

My assumption is also a larger bas of OpenVZ users run on
RHEL-derivatives than Debian, so it is always a safer bet. Running
RHEL6 kernels on Debian boxes since more problematic than migrating to
CentOS, even though I prefer Debian-based distros.

My other concern is the long term viability of OpenVZ on
non-RHEL-based distributions given that Ubuntu dropped OpenVZ support
and it seems that Debian will as well, given that (for good or evil)
LXC seems to be the container-based solution that Debian and Ubuntu
are going forward with.

The only problem I've encountered with OpenVZ on Debian (which is also
a concern) is http://bugzilla.openvz.org/show_bug.cgi?id=1747
