Note: I'm just a user. I'm not an authority here. And what I say is not
necessarily accurate.

I suggested this merely to avoid any confusion.

If your script is going to be included in the pacman tree. People would
expect it to just work no matter what platform/settings they use.

localstatedir is a variable like prefix,libdir ...etc

localstatedir is '/var' in Arch. But It might be '/usr/local/var' or any
other dir elsewhere.

Using '@localstatedir@' instead of '/var' in your script should suffice.
Of course you would have to add the script to a dir in the pacman tree
(maybe contrib) and edit Makefile.am to include your script.

* Used in makepkg and repo-add.
* Portable (e.g: In FreeBSD the command is md5 not md5sum).
