libstore is more than just a thin layer between gnumach devices (hd0 for
example) and the device node below /dev ...

=== want to see some examples?

* you can make a file's content available as some block device (where ''foo''
  is the name of the file to map):
{{{
     settrans -ca node /hurd/storeio -T file foo 
}}}

* you can even ungzip files on the fly (bunzip2 is available as well):
{{{
     settrans -ca node /hurd/storeio -T gunzip foo.gz
}}}

* you can use the ''typed'' store, to create filter chains (of course this
  example is kinda useless since you could use the ''gunzip'' store directly):
{{{
     settrans -ca node /hurd/storeio -T type gunzip:file:foo.gz
}}}

=== available stores
|| device || raw device access (used for access to hd0, etc.) ||
|| file || use a common file as some kind of block device ||
|| zero || kinda empty block device ||
|| task || mach task store backend (TODO: what's this) ||
|| ileave || interleave store (striping) ||
|| concat || concatenate stuff ||
|| remap || remap stuff ||
|| query || TODO: what's this ||
|| copy || TODO: what's this good for ||
|| gunzip || gunzip data on the fly ||
|| bunzip2 || bunzip2 data on the fly ||
|| nbd || network block device (linux compatible) ||
|| url || typed store with url syntax ||
|| typed || typed store (chainable stores thingy) ||


=== even weirder stuff ...
at http://www.kataplop.net/pub/info/projets you can find some effort to make
some crypto store, I will try to make that running within shortly ...
