pmbootstrap reads the file from the master/origin branch of pmaports.git. This way, it will always use the latest fetched version, even if the last checked out master branch (master without the origin/ infront) is not up-to-date. This is likely to happen if a release branch was checked out, as a git pull would then only update the reference from the release branch related to origin's release branch, master's reference would not change.

Release branches do not have a copy of the file, this would just require us to needlessly keep them all in sync.

View it with:

$ cd $(pmbootstrap config aports) # change directory to local checkout of pmaports.git
$ git show origin/master:channels.cfg

For development and testing, it is possible to override the path with --config-channels:

$ pmbootstrap --config-channels /tmp/channels.cfg status
