Comment:
@sbogomolov Please try with my most recent commit and see if the problem with `gtkgreet` persists. As for `INSTALL` vs. `post_install()`, the former lets you change things after they're unpacked into the user's system while the latter doesn't. Since `xbps` doesn't let you install files with a non-root owner except under very specific circumstances, I had to use an `INSTALL` file to change the owner afterwards.
