[explainplease]

Homeshick is indeed great, been using it for years. Every time I've compared it to other solutions, it always comes out on top feature-wise. The other solutions are always missing something, like tracking either files and/or entire directories. Tracking whole directories is very important for e.g. storing an entire ~/.emacs.d in git, and tracking individual files is nice so I can just `homeshick track main ~/.config/some-config-file` without tracking all of ~/.config.

> - use the same source file with different results for different machines (eg. .gitconfig for home and office machines)

I do that by storing each machine's copy with its hostname as a suffix and symlinking it into place on each machine. e.g. ~/.config/anacrontab.systemA gets symlinked to ~/.config/anacrontab on systemA, and the repo contains both ~/.config/anacrontab.systemA and ~/.config/anacrontab.systemB. I can even modify one machine's file from the other machine, and it will be updated on the next push/pull.

But having integrated support for this would be nice.
