Package: usrmerge
Version: 31
Severity: normal
X-Debbugs-Cc: r...@debian.org
Hello,
I'm just filing it as a report here as I'm not sure if this qualifies as
a valida bug. Nevertheless it does break the user's system.

You can try correcting the errors reported and running again
/usr/lib/usrmerge/convert-usrmerge until it will complete without errors.
Do not install or update other Debian packages until the program
has been run successfully.

E: Sub-process /usr/bin/dpkg returned an error code (1)
```
The below occurred inside a Debian Unstable rootfs running
user-mode-linux.
And the reason this fails is because:
```
root@uml:~# cat /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM
hostfs /lib/modules hostfs /usr/lib/uml/modules 0 0
hostfs /var/tmp/Debian-Build/containers hostfs
/var/tmp/Debian-Build/containers 0 0
/swapfile swap swap defaults 0 0
/dev/ubda / ext4 discard,errors=remount-ro 0 1
```
The uml kernel is a modular kernel. The bare boot is built as the
monolithic kernel and everything else as modules, which are then mounted
from the host to the UML guest.
Now, going forward, I can manually fix it by mounting to
/usr/lib/modules and arranging the symlink to the old location in the
guest, something that usrmerge is trying to do.
But I report it here only to keep parties aware and if/whether they have
a better detection and handling of this scenario.
