Fusecompress is a compressing filesystem accessible from userspace and
mountable by unprivileged users.  (Note: this may mean we don't want this note
in the system admin section).  Fedora-11 had fusecompress-1.99.19.  Fedora-12
updates to fusecompress-2.6.  This fixes many very nasty bugs but changes
the on-disk format. '''There is no way to upgrade the on-disk format within
F-12 at this time.'''  Users with fusecompress filesystems will need to move
their data out of the fusecompress filesystem prior to updating, update to F-12,
create a new fusecompress filesystem, and then move their data into the new
filesystem.


I am working on a fusecompress1 package which will only have the
[[Category:Docs Project]]
fusecompress_offline tool.  This will allow migration of data but not allow
[[Category:Draft documentation]]
mounting the old filesystems in F12.  Migration will look like this:
[[Category:Documentation beats]]
 
<pre>
$ # Old fusecompress filesystem had data in ~/.storage and was mounted on
$ # ~/storage
$ # New fusecompress filesystem will have data in ~/.fusecompressstorage and
$ # still mount on ~/storage
$ cd ~/
$ mkdir ~/.fusecompressstorage
$ fusecompress ~/.fusecompressstorage ~/storage
$ find ~/.storage -type f -exec fusecompress_offline1 \{\} \;
$ mv ~/.storage/* ~/storage
</pre>
 
I will update this note with the review ticket and status so we know if we can publish this migration strategy or not.
