Only XDG_DATA_DIRS (or XDG_DATA_HOME) are needed for me in a
container.  Is GIO_EXTRA_MODULES actually needed for anything?  I don't
even have a `lib/gio' directory in my profile.

Yes, please.  IceCat is effectively completely broken without this on
foreign distros and within containers.  It looks like on GuixSD
XDG_DATA_DIRS is set in /etc/profile; I never had to set it manually.

But the presence in /etc/profile implies to me that there are other
packages that require this variable to be present.  Should those
packages also have wrapper scripts?
