I have discussed with Helmut about implementing a sub-hurd-based schroot backend, it should be quite easy, just needs some dive-in to know how to explain schroot how to run sub-hurds.I tried following the documentation at: https://www.gnu.org/software/hurd/hurd/subhurd.html But I could not get a subhurd to boot. I tried: - with the same image as the VM - creating an image with debootstrap - creating an image with crosshurd I always get the message:/hurd/ext2fs.static --readonly "--multiboot-command-line=fastboot root=pseudo-root" --host-priv-port=1 --device-master-port=2 --kernel-task=3 --exec-server-task=4 -T device pseudo-root /lib/ld.so /hurd/exec /lib/ld.so: cannot open bootstrap fileor similar. Any clue?The documentation was for hurd-i386. On hurd-amd64, ld.so is called ld-x86-64.so.1
Now that I could debootstrap, I tried again running a subhurd.With the attached boot-script.hurd (taken from hurd's boot.c and adapted to use /usr/lib/ld-x86-64.so.1) and a subhurd.img (as an ext2 image generated using debootstrap), I get:
demo@debian:~$ boot --boot-script=boot-script.hurd subhurd.img /hurd/ext2fs.static --readonly "--multiboot-command-line=boot - root=pseudo-root" --host-priv-port=1 --device-master-port=2 --kernel-task=3 --exec-server-task=4 -T device pseudo-root/lib/ld-x86-64.so.1 /hurd/exec
Then nothing. I have no idea if something is going on, nor do I know how to proceed to debug things. Any pointers?
Cheers, -- Stéphane
