Changing filesystems

[TheGrammarFreak]

Well, I want to try a few things out. Apparently official Gingerbread stuff, like the Nexus S, is using ext4 on the internal memory. This is something I'd like to try on the CM7 ROM Ali Ba so kindly gave us. My question is thus: how do I go back to yaffs2 afterwards?

EDIT:

And I assume mke2fs will get me to ext2, the tune2fs will get me to ext4, correct? It's going back that really worries me

BALLS! This is in the wrong place.

Hmm, I don't think you wanna try this. We are talking raw NAND here, without controller for relocation/marking of bad blocks. Yaffs2 can do that, ext on the other hand can't. Also erase block (sector) on NAND is 128kB which is really big comparing to 512B on disks and "flash" cards with own controller.
