Avoid reinventing the wheel. ;-) As far as I understand it, LFS does
many of the things like wear-levelling by design. It may require minor
adaption, but the principle should be OK. As Garrett pointed out,
writing a BSD version of JFFS, that is compatible with the Linux
implementation, is a good idea. BTW: JFFS is based on the principles of
LFS, AFAIK. You can also think about a BSD version of squashfs. Squashfs
is read only but supports compression and is very space efficient. It
seems to be easy to implement, so implementing squashfs is a good
exercise. You may have a look at OpenWRT, that uses JFFS and squashfs
