sshd wants to change permissions on /dev/ttyXX when you login so that only
you can write to it (or your group)  - i originally dealt with this in
flashdist by making /dev/ttyXX symbolic links to the actual devices at
writeable (mfs) /var/run/dev/ttyXX. 

unfortunately, sshd uses login() to write your login entries to utmp, which
fails if ttyname() decides that your device is not an actual character device.
this was a problem with flashdist, symbolic links caused ttyname() to fail
so utmp was always empty - and then i moved /dev to full mfs
