Package: debootstrap Version: 1.0.128+nmu2 Severity: normal Tags: patch Control: affects -1 + mmdebstrap
Hi, steps to reproduce: runuser -u debci -- mmdebstrap --variant=custom --mode=unshare --setup-hook='container=lxc debootstrap unstable "$1"' - chroot.tar Run this inside a privileged docker container (like in a salsaci autopkgtest) and observe how the following files are missing from chroot.tar: /etc/mtab /root/.ssh /run/lock/subsys /var/cache/private /var/lib/private /var/lib/systemd/coredump /var/lib/systemd/pstore /var/log/README /var/log/private All of these would be created by systemd-tmpfiles. They are not created because (after setting SYSTEMD_LOG_LEVEL=debug): /proc/ is not mounted, but required for successful operation of systemd-tmpfiles. Please mount /proc/. Alternatively, consider using the --root= or --image= switches. This is because debootstrap runs "mount -t proc proc /proc". This does not work inside an unshared mount namespace inside privileged docker (like salsaci). See this other bug for a handy table about how to mount /proc: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1030625#16 As shown in that table, this can be resolved by falling back to bind-mounting /proc if mounting it normally didn't work. I implemented that in this merge request: https://salsa.debian.org/installer-team/debootstrap/-/merge_requests/91 Thanks! cheers, josch
