Ignore pkgs during initial bloom-release: master vs main branch
As part of the release process for a new package, bloom-release will git clone the release repository and start adding branches and commits.
bloom-release seems to assume master is the default/main branch, and will create one if it doesn't exist.
For release repositories created on Github, and unless users have configured otherwise, new repositories will have their default branch set to main now instead of master.
This works OK for regular releases (as master will just be another branch to git and Github, and Bloom is able to find everything it needs just fine), but in case packages need to be ignored / excluded from an initial release, a ${ROS_DISTRO}.ignored file should be added to the master branch, or Bloom will not find it (it creates a master branch and ignores main completely, including the .ignored file in it).
I've not been able to find a command line arg which lets me specify the branch Bloom should use for this.
Is there a way to do this, or should I be approaching this in a different way?
