Over the last couple of nights, I've added support for "profiles"
to schroot, and one of these is a "desktop" profile. Currently,
this is the fstab for this profile on Linux:
# fstab: static file system information for chroots.
# Note that the mount point will be prefixed by the chroot path
# (CHROOT_PATH)
#
# <file system> <mount point> <type> <options> <dump> <pass>
/proc /proc none rw,rbind 0 0
/sysfs /sysfs none rw,rbind 0 0
/dev /dev none rw,rbind 0 0
/home /home none rw,bind 0 0
/tmp /tmp none rw,bind 0 0
/var/run /var/run none rw,bind 0 0
I opted to bind mount the whole of /var/run to get other stuff
like dbus sockets. However, doing this more selectively might
reduce the change of nasty problems such as things in the
chroot interfering with services on the host.
Do you think there are any other things that need binding into the
chroot under e.g. /var that we've missed?
The same applies to files copied in with "copyfiles"--is there anything
else here we should add? Currently this is just resolv.conf, but any
other stuff needed by X or other things in the user's session could be
copied here.
Regards,
Roger
