fstransform is a tool to change a file-system from one format to another, for example from jfs/xfs/reiser to ext2/ext3/ext4, in-place and without the need for backup.

Hi, I've used fstransform a couple of times when a Linux distro I was trying wouldn't install to reiserfs and I wanted to use reiserfs. So, I installed to ext? and used fstransform after installation to get what I wanted. It worked well, although I don't remember the few extra steps, like changing fstab, possibly regenerating an initrd.img This is a very nice piece of software, thanks for your work.
