Not sure about mint (I don't use it), but Ubuntu has /lib/init/fstab: # /lib/init/fstab: static file system information. # # These are the filesystems that are always mounted on boot, you can # override any of these by copying the appropriate line from this file into # /etc/fstab and tweaking it as you see fit. See fstab(5). While in ubuntu it does NOT mount cgroup, mint might use something like that. Also, in ubuntu there's /etc/init/cgconfig.conf, which IS responsible for mounting cgroup. In my experince it doesn't work very well. Or rather, it STARTS very well, but once I add cpuset to /etc/cgconfig.conf, it won't to stop cleanly. So I override it with my own mount/umount commands. A similar upstart/service/inittab might do the same on mint. -- Fajar ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users
