udf filesystem on sd cards
 

Now that i've got my n800, i'm starting to get into the dev environment. First thing I was thinking of adding is support for udf formatted sd cards. This would allow for greater Linux compatibility (symlinks, permissions), yet still retain the ability to mount the cards on a windows host.
So this will involve porting udftools, along w/ the matching kernal modules. And maybe writting a gui front end to mkudffs.
This would make it easier to install/move packages to sd cards, as many apps make use of symlinks and such, which fat32 cant handle.
Anyone else see any merrit in this? If so, I'll go ahead and put the extra effort into it to make it user friendly. Also, am I right about windows being able to use read/write udff media? I know dvds are udf.

Why not just use ext2? It already works, the modules are already on the device and if you really need to access it on windows use this -->

Allows read and write access to ext2 partitions....

The idea is to be compatible w/ any arbritrary computer (at a friends house, the library, work laptop), where you may not be able to install additional software. Therefore it's best to stick with a filesystem that's already present on most computers. I believe that udf is almost universal in all current systems.

I'm suprised that udf isn't on more gaadgets, esp since it is more efficient on high capacity media.

This sounds like an interesting idea. I haven't worked much with UDF so I'm not aware of any pitfalls - except for this possible one: Is UDF any good as a read/write filesystem? Usually an UDF filesystem is prepared all at once, then burned to media. I guess even for rewritable DVDs you don't really update files indivdually at an inode level.. or do you?

Actually, DVD-RAM is UDF, and they are writable at the sector level. I've ran UDF filesystems on regular Linux boxes, and I haven't ran into any major performance headaches.

My main concern is, how good does UDF read/write work with other OSs. I've only used them with DVD-Ram on Windows.
