Bug#1133276: mkosi: Building Debian Images fails (kmod not found)

[Manuel Traut]

Package: mkosi
Version: 26-2
Severity: normal
X-Debbugs-Cc: manut at mecka.net

Running mkosi on Debian/sid for building a Debian image fails:

$ mkosi --distribution debian --release sid --package linux-image-amd64 --output disk
‣  Running depmod for 6.19.11+deb14-amd64
‣ depmod not found.

Expected output (with mkosi from git):

Automatically determined minimal disk image size as 473.6M, current block device/image size is 473.6M.
File '/work/home/manut/.cache/mkosi/mkosi-workspace-gu1xq3hv/staging/disk.raw' already is of requested size or larger, not growing. (473.6M >= 473.6M)
No changes.
‣ [main]  /home/manut/x86/disk.raw size is 473.7M, consumes 315.9M.
