[Lxc-users] Silence lxc-unshare warning when removing cgroup

2011-08-03 Thread Serge E. Hallyn
If ns cgroup is mounted, then when lxc-unshare runs, the kernel automatically creates a new cgroup for the task. So lxc-unshare tries to delete it. But if ns cgroup is not mounted, that cgroup does not get created, and now lxc-unshare spits an error. Author: Serge Hallyn Bug-Ubuntu: https://bugs

[Lxc-users] [PATCH 2/3] make lxc-netstat work when /etc/mtab is not /proc/mounts

2011-08-03 Thread Serge E. Hallyn
like lxc-ps and lxc-ls, lxc-netstat breaks if there is not an 'lxc' cgroup mount and /etc/mtab is not a link to /proc/mounts. Author: Serge Hallyn Bug-Ubuntu: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/819319 Forwarded: no Index: lxc/src/lxc/lxc-netstat.in

[Lxc-users] [PATCH 1/3] fix lxc-ls with mtab != /proc/mounts

2011-08-03 Thread Serge E. Hallyn
The cgroup mounts created by cgroup-bin do not show up in /etc/mtab. lxc-ls, as lxc-ps before it, assumes that /etc/mtab is symlinked to /proc/mounts. Author: Serge Hallyn Forwarded: no Bug-Ubuntu: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/819319 Index: lxc/src/lxc/lxc-ls.in
