Comment 7 for bug 1974177

Thanks.

1) Following line in debian/tests/unshare will break Debian (since the script runs with "set -e"):

[ "$distro" = ubuntu ] && umask 022

Either use || or an if-clause. Besides that, you can just source /etc/os-release and then use the ID variable.

2) Running the unshare autopkgetest with a kinetic schroot fails:

autopkgtest [12:48:47]: test unshare: [-----------------------
+ [ -z x ]
+ grep -q ^1$ /proc/sys/kernel/unprivileged_userns_clone
+ dpkg --print-architecture
[...]
+ mmdebstrap --mode=unshare --variant=apt kinetic /tmp/autopkgtest.4hxHnh/autopkgtest_tmp/chroot.tar
W: unshare syscall failed: Operation not permitted

Does it need more checks or does it need to declare to be better isolated?
