I think it was simply the unavailability of LVM, e.g. if there are
no volume groups, lvm-snapshot kinda doesn't work.

I solved this by forcing builds to take place in /build and mounting
a 10Gb LV as /build in every chroot. The possible double use of the
same filesystem by multiple chroots was the reason for #478044.
