Re: any way to apply tag across all branches in repository?

What's "ncgl"?  Another branch at the same tip as "arch"?

Oops, missed a replace.  "ncgl" is my main branch.

Ok, you tagged main, and previously arch was at the same state,
so 'git describe' printed out 'my_tag' for both of them.  Now,
the arch branch is ahead of main by one commit, so you get an
expanded string from 'git describe' (the meaning of which I
described earlier, above).

Now we add another tag to the main branch:

[cfriesen@localhost linux]$ git tag -m 'a test tag' my_tag2 main
[cfriesen@localhost linux]$ git describe main
my_tag
[cfriesen@localhost linux]$ git describe arch
my_tag-1-g4c8dfa7

I assume that since there were no code changes on the main branch,
it doesn't think that there is any difference between the two tags.

Right.  There is no difference.  You created another tag pointing at
the same revision as the first tag.  Here's something else to try:

Starting to make sense?

Yep.  I still need whatever identifier I use to be associated with the
head of each branch.

Based on the discussion (thanks for the explanations, by the way) I
don't see any option other than looping through each branch and using
tags with the branch name embedded in them to ensure uniqueness across
the repository.
