We could have an explicit list of them in util/i386/pc/grub-setup.c
same way as we currently have a list of supported partition tables.
This approach has a drawback of needing to manually add new
filesystems to yet another list but it has a safeguqrd to install only
on configurations which we have tested. If user needs to install to
another FS he can test and submit a patch. The only problem I see is
if FS is in grub-extras. In this case grub-setup wouldn't be able to
identify it and would fail installing to prevent FS damage. This is
part of larger problem of grub-utils with external modules. As a
possibility grub-setup can ask host OS about the target filesystem
(cumbersome) or we could implement module loading in grub-setup (using
shared library approach perhaps?)
