Hi!
It would like to install SUSE Linux 11.1 on an ASUS Eee PC S101 with a Solid State Disk. For A SSD I would like to use a file system that is optimized for SSD/Flash Disks like JFFS2. The question is is it possible to format the disk with jffs2 during the installation? Which tool do I need to format further flash disks with jffs2? I tried to search with “zypper se jffs2” for tools but didn’t find anything.
Thanks for your help!

suggests that JFFS2 is not a suitable filesystem for a SSD. In fact if it appears like a disk, then the translation has already been done for you and you should treat it like a block device.
In several wiki articles it is recommended to use a journaling flash file system instead of ext3 or something because of high write operations with conservative journaling file systems. An alternative would be a ext2 because it has no journal. But don’t wanna miss a journaling file system anymore so I thought JFFS2 would be a good choice for SSDs.
It is better to use ext2 instead of JFFS2 because, nowadays, most good NAND devices come with built-in controllers for wear-leveling. (I even suggest mounting option like “noatime” etc. to reduce “smaller” writes that are costlier).
Yeah! I googled around a bit and most people chose ext2 for their SSD drive. So I don’t understand the recommendation in the wiki articles. Well I give it a try. Other people say the upcoming BTRFS should be a good choice for SSDs or even ZFS if it gets a GPL license one day (hopefully).
Information goes out of date or is just plain wrong for a different situation.
