In the meanwhile I consider the missing /dev/pts mount a bug in the
script which sets up the chroot and have reported it as such:
https://bugs.debian.org/788580 (FTBFS = Debian slang for "Fails to
build from source").

The only thing which is IMHO left on the zsh side is why the testsuite
fails (instead of e.g. skipping the according tests) if /dev/pts/ptmx
is missing. Is this on purpose? Or just never occurred before? (Mostly
curious. :-)

		Kind regards, Axel
