Below is an example of repeating mount --bind and
getting two listings. I have experience where
running the commands repeatedly will add numerous
duplicate mounts resulting eventually in the
no ptys error which gets fixed by a reboot
or umount -l and removing the entries.
To avoid this I add some tests.
If the system is then reformatted it will
still have a reference to /dev from
mount --bind, so the script test will pass,
but no dev/pts or dev/shm will exist resulting
in the error.
Is it OK to explicitly create
dev/pts and dev/shm before mount --bind ?
This will fix my situation.
