- We used to use `# tag "linux"` in Homebrew/linuxbrew-core for the ~50
Linux-only formulae. As of
6578a4aa86,
we're using `depends_on :linux` to have a consistent syntax between
Linux and macOS.
- Therefore, we have to change the search string for Linux-only formulae
that determines whether or not `brew bump-formula-pr` deletes the bottle
line.
