I've given this a quick test, while it seems to fix the initial problem
with umounting /dev/ptmx, it does introduce a new one - trying to open
an xterm (KDE5's konsole to be exact) doesn't open a shell (the shell
window remains totally empty) and trying to ssh into the system fails
with "PTY allocation request failed on channel 0", logging in via a
real tty and creating a new pbuilder chroot from there succeeds.
