Ah, yes, that is bad.  Thanks.

Ok, useful to know.

Debian's tools could use https://git.gnome.org/browse/linux-user-chroot
for this.  It's intended for exactly this kind of purpose. 
uses it to ensure that *only* the build directory is writable,
else has a read-only bind mount.  (It'd be even better if I could
hide the home directory to ensure the build can't read e.g. your ~/.ssh,
but that's hard to do generically)

What's the current state of Debian ADT versus
https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests ?
I think last we talked you were amenable to DBus installing
InstalledTests .test
files?  And someone was looking at building an automatic bridge from
InstalledTests to ADT, right?
