Hello Debian sysvinit maintainers, hello Matthew, I wanted to send a friendly ping about bug #1142015 which I submitted two weeks ago for a MR I submitted a month ago on salsa.
According to the CI pipeline of [1] this is the last remaining issue before my patch to debvm is able to output directly bootable Debian GNU/Hurd images built on Linux with packages directly from the archive. Since the default value of $DPKG_ROOT is the empty string, I believe that it is fairly trivial to verify that my patch cannot result in any functional behaviour difference when installing the package the normal way (without dpkg --force-script-chrootless) and should thus be safe to apply. My exams for this semester are over now and I'd like to spend my free time on the GNU/Hurd topic again, so I wanted to send you a ping about it. No pressure! :) But if you are just short on time, I can also offer to NMU orphan-sysvinit-scripts for you. Thank you for maintaining orphan-sysvinit-scripts! cheers, josch [1] https://salsa.debian.org/helmutg/debvm/-/merge_requests/39 Quoting Johannes Schauer Marin Rodrigues (2026-07-13 22:56:38) > Source: orphan-sysvinit-scripts > Version: 0.23 > Severity: wishlist > Tags: patch > > Hi, > > to create a Debian GNU/Hurd chroot from Debian GNU/Linux, so called > "chrootless" or --force-script-chrootless (the dpkg option) has to be > used because Hurd binaries cannot be run on Linux.
