Any thoughts on moving from jffs to ubifs ?
Seems like ubifs has really improved in stability recently.
I think we are ready to do this without too much hassle - but first
let's wait until someone has actually made and published a build and
offered some kind of loose commitment to doing this on a regular
basis.
At that point, the relevant links are:
http://wiki.laptop.org/go/UBIFS_on_XO
http://wiki.laptop.org/go/UBIFS_initial_experiments
I think the only remaining question from the earlier work was about
the readings given by df -- but upstream justified that behaviour, so
that is no longer an outstanding issue.
The work will then be to:
- modify the build system to build partitioned images (we need jffs2
for /boot) -- I wonder if this will cause complications given the OLPC
versioned filesystem layout...
- modify livecd-iso-to-xo to make a ubifs filesystem for the root,
and jffs2 for boot
- teach dracut how to boot from UBI
