142 # in the global zprofile, or source scripts of other shells in the global
143 # zprofile, that may rely on our desired dir structure and vars pointing
144 # to it. for example, `flatpak-bindir.sh` in the Arch Linux flatpak
145 # package references $XDG_DATA_HOME with no fallback. since we do special
146 # handling for these vars before we export them, we're forced to do it all
147 # here instead of at the top of the zprofile.
