[Thinstation-general] chroot exit leaves mounts mounted

[Todd P. <pf...@rh...>]

I'm using thinstation 6.2-Stable, git cloned 2022-04-01.

I'm doing builds on a CentOS 7 host.

Something with setup-chroot is faulty.  When I exit from setup-chroot, it 
does not unmount things like it's supposed to.  I can clearly see the code 
in setup-chroot in function do_unmounts() that is supposed to do 
the unmount, and I can see from where this is called, but it's not doing 
its job.

This is then somehow leading to various problems.  We've seen both /dev/ 
and /dev/pts/ go empty while I've been working with ts6.2 recently.
