how to share a file between 2 repositories? Hardlinks?

This sounds like vc-mode detecting that it’s a hardlink and using the
"canonical" location -- which wasn’t the file you opened, but the other
repository.

I don’t have a good solution for the problem: I tend to just copy the
bibtex files and merge them manually from time to time using M-x
ediff-merge.

An option could be to use a common bibtex repository, always commit the
changes to the bibtex file individually in the work repository and
export+import those changes to the other repository. Then you can always
import+merge the bibtex repo in all other repos.

To automate it, you could create a commit hook that does the
export+import; in .hg/hgrc:

[hooks]
commit = hg log -r $HG_NODE --template '{files}' | grep -q 'bibtex.bib' && hg export $HG_NODE > /tmp/bibtex.patch && hg -R ../bib import /tmp/bibtex.patch && rm /tmp/bibtex.patch || true

Best wishes,
Arne
