If you want to know details about how the schroot is configured on the
porterbox, only the administrators of that machine can tell you. I was
using the porterbox to figure out why one of my packages fails to build
in the Debian build system for gnu/hurd. I did not do any tweaking of
the configuration myself, but I have no idea if the porterbox admin has
done something.

As mentioned in the bug report, outside the schroot there is no problem
renaming directories in /tmp.

Yes it is hurd specific. The package that fails to build on gnu/hurd due
to this issue builds without problem on all other architectures. This
was the reason I added

User: debian-hurd at lists.debian.org
Usertags: hurd

to the bug report.

This issue is the cause of failed package builds, see e.g.

https://buildd.debian.org/status/fetch.php?pkg=myproxy&arch=hurd-i386&ver=5.9-1&stamp=1358177698

This issue can be seen on both a gnu/hurd debian porter box and four
different gnu/hurd sbuild hosts, so it seems to be a general problem
affecting all gnu/hurd machines.

I am sorry I can not provide more information, but I am no expert in
gnu/hurd. I hope there is some gnu/hurd expert that can provide input.
