Public bug reported:
After successfully creating a loong64 chroot with debootstrap, schroot
appears to hang when trying to use it.
$ schroot -c test
HANG
I have attached an strace.
This does not occur in Resolute and copying the binary across to Noble
(and restarting systemd-binfmt) solves the issue. I also compiled
upstream 11.0.1 and this works fine.
