Unless I'm proven wrong, I'd say the following two things are needed for
read-only root:
- dhclient has to be changed to create resolv.conf somewhere else. It
should also be fixed to not loop around if it can't create resolv.conf,
but that's a separate question.
- mount ptyfs and drop /dev/tty* (not all, but the ptys). This works for
most software, would be nice to know what breaks to fix that to use
openpt and friends.
