Hi!

sbuild 0.91.5 keeps trying to use unshare backend on hurd and fails miserably:

Error reading configuration: Undefined subroutine &Sbuild::Utility::SYS_unshare called at /usr/share/perl5/Sbuild/Utility.pm line 444.
E: unshare failed: 
Error reading configuration: failed to open /proc/sys/kernel/unprivileged_userns_clone at /usr/share/perl5/Sbuild/Utility.pm line 455.

even though I specifically put this in /etc/sbuild/sbuild.conf:

$chroot_mode = "schroot";

But if I specify --chroot-mode=schroot, there is no such problem.
