s/thought/uses/

Nobody's going to add support for a file system they don't use, 
and nobody boots Guix from JFS.

…yet. :-)

Spare time sucks, consider contributing JFS support to Guix 
instead.

Assuming it's a pretty conventional Linux file system:

- Guix's Linux-Libre kernel already builds the module 
  (CONFIG_JFS_FS=m)
- it just needs to be added to the initramfs when booting from JFS
- jfsutils needs to be packaged for Guix and a static fsck added 
  to the initramfs
- some code must be added to (gnu build file-systems) to read JFS 
  labels & UUIDs: Guix does not use C tools to do this like other 
  distributions.

If you're completely new to Guix that might sound daunting, but 
it's honestly not that hard and you should get plenty of help on 
the mailing list and/or on IRC.

Kind regards,

T G-R
