Thanks Stéphane,

Here's what's there:

grep proc /proc/mounts:

proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0

systemd-1 /proc/sys/fs/binfmt_misc autofs 
rw,relatime,fd=36,pgrp=1,timeout=0,minproto=5,maxproto=5,direct 0 0

xenfs /proc/xen xenfs rw,relatime 0 0

I don't think I can safely remove any of those.  Any other ideas?
