@gonzopancho:
I'm actually looking at using ZFS to do this, rather than the 2 slice nano setup.
ZFS let's one keep multiple copies, and provides transparent compression on/off the SD card.
First I have to prove (internally) that it is as reliable.
@gonzopancho:
As above, I'm investigating running ZFS as a first step to moving on from the nanobsd past and its restrictions.
If it pans out, then likely that a "3.0" version of the pfSense software will run something a lot like 'freebsd-update', rather than the BWOS-like releases of today, and likely also something a bit more modern for a configuration system and GUI than the large mass of PHP that defines the product now. This should help us address some of the security shortcomings in the current codebase.
NO decision has been taken (yet), it's just time to re-think the direction.
+1 for ZFS
