yes, remember how in one of my last mails I ran into an error because the hurd preinst was missing a check for [ -z "$DPKG_ROOT" ]. In chrootless mode, maintainer scripts are run but without a chroot call, so the tools from the outside are used to process the scripts and the $DPKG_ROOT tells the tools what to do. So either the preinst or the postinst could gain a snippet like this: mkdir -p "$DPKG_ROOT/servers" "$DPKG_ROOT/dev" for f in /servers/exec /servers/startup /dev/console; do touch "$DPKG_ROOT/$f" done > > The symlink chain is this one: > > > > /usr/libexec/runsystem -> /etc/hurd/runsystem -> /alternatives/runsystem -> > > /etc/hurd/runsystem.gnu > > > > Should that last one be linking to /etc/hurd/runsystem.sysv? > > Yes, I don't see why it's not doing that, isn't the alternative like > this? > > Selection Path Priority Status > ------------------------------------------------------------ > * 0 /etc/hurd/runsystem.sysv 10 auto mode > 1 /etc/hurd/runsystem.gnu 5 manual mode > 2 /etc/hurd/runsystem.sysv 10 manual mode Since I cannot boot into this system, I'm afraid I cannot run update-alternatives to get output like the above. :) But here is my /var/lib/dpkg/alternatives/runsystem: auto /etc/hurd/runsystem halt /sbin/halt poweroff /sbin/poweroff reboot /sbin/reboot /etc/hurd/runsystem.gnu 5 /sbin/halt-hurd /sbin/poweroff-hurd /sbin/reboot-hurd So this is missing entries for /etc/hurd/runsystem.sysv. The hurd.postinst only sets up the entry for runsystem.gnu at priority 5. So I looked at the initscripts.postinst from sysvinit and that one also calls "uname" :D I'll have to go through the postinst scripts of the essential packages and find out who calls uname and then send patches. Until then I can hack around it. > > If I do that I get: > > > > /usr/libexec/runsystem.hurd: 117: Pipe call failed > > You are probably also missing /servers/socket/1 No, I have that. Check here: $ curl --silent https://people.debian.org/~josch/hurd.tar.xz | unxz | tar tv | grep /servers/socket/ drwxr-xr-x root/root 0 2024-02-07 17:12 ./servers/socket/ -rw-r--r-- root/root 0 2024-02-07 17:12 ./servers/socket/1 I checked what should be in there according to exodar.debian.net and also created the remaining entries manually, so now I have: $ ls -lha /mnt/servers/socket/ total 8.0K drwxr-xr-x 2 root root 4.0K Feb 8 07:49 . drwxr-xr-x 3 root root 4.0K Feb 7 17:12 .. -rw-r--r-- 1 root root 0 Feb 7 17:12 1 -rw-r--r-- 1 root root 0 Feb 8 07:49 2 -rw-r--r-- 1 root root 0 Feb 8 07:49 26 lrwxrwxrwx 1 root root 1 Feb 8 07:49 inet -> 2 lrwxrwxrwx 1 root root 2 Feb 8 07:49 inet6 -> 26 lrwxrwxrwx 1 root root 1 Feb 8 07:49 local -> 1 But the problem remains the same. > > My final goal is to have debvm-run (which is just a wrapper around > > mmdebstrap) > > create a disk image that can be run with debvm-run (which is just a wrapper > > around qemu).

But now think about this: if support for this is in debvm and then autopkgtest has debvm support, then you can build hurd packages on linux using sbuild's autopkgtest backend or more directly via sbuild-qemu. That would be super cool, no? :D > > I'm probably missing more customizations to make this work. Where else other > > than in debootstrap should I look?

I hope you have another theory! Thank you so much for your help!! :) cheers, josch
