Include FS for SD cards

[uzytkownik]

There are many FS suitable for use on SD card:

• NilFS(?) (included in kernel 2.6.30)
• LogFS
• ...

Currently used ext2/3/(v)fat were designed and optimized for HD.
I'd guess including one in SHR Feed (module, utils etc.) would benefit users much.

Quote: "...Another advantage of this approach is that the log offers a coherent historical view of all the operations done in the disk in the past. This is called "continuous snapshotting" - snapshots of modifications done in all the filesystem at any time are created automatically due to the log-structure design, with no requirement of intervention from an admin, and with the filesystem size as the only limit. NILFS2 allows to access those snapshots and even mount them (on read-only mode)..."

[ Importent note: ]
As matter of fact, I discovered that on my Debian Lenny system, the shutdown script that unmounts did not recognize the new file system, and it was not unmounting it. It took me days to discover this, then I wrote in a script to unmount Nilfs on shutdown myself.

[ Very fast image reverts, but in case you want to use it like this, then your data ought to be on a separate partition: ]
Here’s another one: if you use virtual machines, maybe you snapshot
the file system the virtual machine’s files reside on. Then, if you
end up wanting to undo it, you can, just by recovering the old version of the virtual machine’s file.
