Dear maintainer,

During a test rebuild for building packages with
`Rules-Requires-Root: no` as the default in `dpkg`,
rsbackup failed to rebuild.

The above is just how the build ends and not necessarily the most
relevant part. If required, the full build log is available here:

https://people.debian.org/~nthykier/rrr-no-as-default/logs/1039488.gz

You can find common solutions at
https://people.debian.org/~nthykier/rrr-no-as-default/docs/solutions.md

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

If this package is listed in
https://people.debian.org/~nthykier/rrr-no-as-default/docs/static-ownership.list,
then please just set `Rules-Requires-Root: binary-targets` to the source
stanza of `debian/control` as a fix to this bug.

If this package is listed in
https://people.debian.org/~nthykier/rrr-no-as-default/docs/maybe-misbuilds.list,
then the package was deemed at risk for misbuilding (having wrong
ownership) but had a FTBFS problem we tested it. Please test whether the
package works with `Rules-Requires-Root: no` validating that the
resulting deb has the correct ownership for all paths in the deb.

The goal is to have the default changed in `dpkg` either in `Trixie` or
`Forky`, depending on progress and feasibility with the release schedule
for Trixie.

Thanks,


PS: The builds were performed in mid-November. If you fixed the problem
between between then and this bug being filed, then please just close
the bug with the version it was fixed in.
