Reading lib/Sys/Filesystem/Linux.pm, the full list of "special"file system
types is

    binfmt_misc, debugfs, devpts, fusectl, fuse.gvfs-fuse-daemon,
    mini_fo, nfsd, proc, procbususb, securityfs, swap, sysfs, tmpfs,
    udev

There's lots of diagnostic output in the build1 log including

  # filesystem - mounted - special - device - options - format - volume - label 
- type
  # / - 1 - 0 - /dev/vda1 - rw,relatime,errors=remount-ro,data=ordered - ext4 - 
1 - 1 - ext4

and a long list of other file systems like things under 
/srv/workspace/pbuilder/61616.

It looks like these come from either /etc/fstab or /proc/mounts. So
perhaps the difference between the chroots is in /etc/fstab ?

Still not sure how much of this can be expected from a 'sane' build
environment...
