unshare: allow persisting namespaces
For nsenter(1) we already support namespace specification by file
(e.g. bind mount to namespace /proc/[pid]/ns/[type] file). For
example:
# nsenter --uts=/some/path
This patch extends unshare(1) to setup the bind mount for specified
namespace, for example
# touch /some/path
# unshare --uts=/some/path hostname FOO
# nsenter --uts=/some/path hostname
FOO
Note that the problem is mount namespace, because create bind mount
to ns/mount file within unshared namespace does not make sense.
Based on patch from Lubomir Rintel <lkundrak@v3.sk>.
