When building with mkosi I would get the following:
[1/477] Generating version.h with a custom command
fatal: detected dubious ownership in repository at '/work/src'
To add an exception for this directory, call:
git config --global --add safe.directory /work/src
and then the tag would be generated as 'v254-'. This is obviously some problem
with the setup, but we should handle this gracefully. Let's fall back to 'v254'
instead.
In the case where we have a repo but no tags, use --dirty=^ too, as in the case
with tags.
I tested four cases:
- normal checkout
- checkout with .git removed
- checkout with .git chowned to root
- checkout wiht all tags removed
