Bad format. If anything, it should contain mount IDs (if you want to have
union-mount you need those, just to be able to take away components).
The following might go:
1 / / ext2 /dev/hda1
2 /var/spool/mail / ext2 /dev/hda2
3 /proc / procfs
14 /gaol/var/spool/mail / ext2 /dev/hda2
15 /gaol/proc / procfs
42 /gaol/lib/libc.2.1.3.so /lib/libc.2.1.3.so ext2 /dev/hda1
...
IOW, ID + mountpoint + location of root in its tree + fs type + fs-specific
parameters. That at least allows to reproduce the namespace. And yes, IMO
"device" is fs-specific parameter.
