While working on a complex package change, I wish I was able to
"pass-through" additional options to sbuild when working with ratt.

In particular, I wish I could invoke 'ratt' in a way that would allow me
to use the options '--extra-package=/path/to/my/custom/package',
'--extra-repository=...', '--extra-repository-key=...' and
'--add-depends' options, so that I can force the rebuild to pickup some
locally changed "lower level" packages.

I envision a ratt invocation like this:

ratt go-md2man_2.0.0+ds-1_multi.changes \
   --extra-repository=deb http://deb.debian.org/debian  experimental main' \
   --extra-package /srv/scratch/golang-github-containers-common-dev_0.14.4+ds1-1_all.deb


Would such an extension to ratt be agreeable?

Hi,

I think you can configure it through sbuildrc? it could be in
~/.sbuildrc or with SBUILD_CONFIG env.
