I am trying to quit pbuilder/cowbuilder to work on packaging and so use
sbuild directly. Currently it is the version 0.81.2 on a Sid system. So after looking at
sbuild-createchroot(8) manpage, I used the command:
$
sbuild-createchroot --chroot-mode=unshare --make-
sbuild-tarball ~/.cache/
sbuild/unstable-amd64.tar.gz unstable $(mktemp -d)

If I understand well, it is a Perl script that tries to execute some 'newuidmap' command that is part of the uidmap package and is not currently installed, neither present in the sbuild depends.
I am trying to follow /u/s/d/sbuild/README.Debian that does not mention anything on this.
