Package: piuparts Severity: wishlist It would be great if piuparts supported root-less operation, ideally in a less complicated way than via podman+docker.
Conversation in #debian-qa suggests the are various options for building on top of infrastructure that's provided by other packages, e.g. sbuild, autopkgtest or mmdebootstrap. <josch> Jelmer, h01ger: I'd second what helmut said. With mmdebstrap you get the equivalent of "lxc-usernsexec -- lxc-unshare -s 'MOUNT|PID|UTSNAME|IPC' -- /usr/sbin/chroot ./debian-rootfs /bin/bash" but without having to depend on lxc -- You can see a variant of this in the mmdebstrap man page where mmdebstrap is used as a wrapper of debootstrap to fix #829134. That way you can run debootstrap without needing root: mmdebstrap --variant=custom --mode=unshare --setup-hook='env container=lxc debootstrap unstable "$1"' - debian-debootstrap.tar Alternatively, if you want to depend on neither lxc nor mmdebstrap, a number of tools implemented a simple unshare backend already using code like this: https://salsa.debian.org/debian/sbuild/-/blob/main/lib/Sbuild/Utility.pm#L382 or this: https://salsa.debian.org/ci-team/autopkgtest/-/blob/master/virt/autopkgtest-virt-unshare#L131 re-using the unshare functionality of either mmdebstrap, sbuild or autopkgtest would probably be best there was some discussion whether those three tools could share some code here: https://salsa.debian.org/ci-team/autopkgtest/-/merge_requests/138#note_306768 unfortunately i don't see how if somebody wants to work on unshare support for piuparts, feel free to ask me questions about unshare or its implementation in mmdebstrap, sbuild or autopkgtest the other people in the know are smcv and jochensp oh and there is this as a standalone replacement: https://gitlab.mister-muffin.de/josch/user-unshare/src/branch/main/user-unshare -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') merged-usr: no Architecture: amd64 (x86_64) Kernel: Linux 5.18.0-4-amd64 (SMP w/2 CPU threads; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages piuparts depends on: ii debootstrap 1.0.127 pn debsums <none> ii libjs-sphinxdoc 4.5.0-4 ii lsb-release 11.2 ii lsof 4.95.0-1 ii mount 2.38.1-1 pn piuparts-common <none> ii python3 3.10.6-1 ii python3-debian 0.1.47 Versions of packages piuparts recommends: pn adequate <none> Versions of packages piuparts suggests: pn docker.io <none> pn schroot <none>
