Do these builds (specifically the Gotham Popcornmix build) support booting from NFS ?

I've followed the guide here; http://forum.xbmc.org/showthread.php?tid=149607 and it just keeps booting to ;

Error in mount_flash: mount_part: Unknown filesystem

I've checked all the cmdline values and they look correct, I can also mount the folders via an existing Openelec installation I have, so it seems the share is ok too..

As the author of that How-To, I'm no longer of the opinion that it's worth the effort using NFS to boot a Pi, although NFS is certainly still useful for /storage.

Note that auto-update is no longer supported by OpenELEC Gotham builds, not even when dropping files into the Update folder manually. Any non-local boot device will result in the update being abandoned with an "unsupported" message, so really there's no benefit I can think of for using NFS (or SMB, or even USB) to boot the Pi. Stay with boot=/dev/mmcblk0p1, put SYSTEM on your SD card FAT partition, and use NFS for /storage (disk=NFS etc.).
