What's different about /tmp inside the chroot?  Is it bind mounted
(or the hurd equivalent) inside the chroot?  What is the configuration
you are using for this chroot; did you make any particular
customisations?

Can you reproduce this manually without involving schroot?

I strongly suspect that this is a hurd-specific bug or configuration
issue; while we might be able to work around such issues by avoiding
it in the default hurd configuration, it would be good to know to
start with what is actually causing the failure here.

Regarding the default configuration: The schroot source code
contains system-specific configuration templates
(etc/profile-templates) for linux and freebsd.  There are currently
no hurd templates, and if anyone wanted to create them that might
give a better default experience for hurd users.


Thanks,
Roger
