I'm PXE-booting a Ubuntu 10.10 system, where I specify the kernel parameters as follows:

append root=/dev/nfs initrd=ubuntu-boot/initrd.img-2.6.35-24-generic nfsroot=11.22.33.44:/data/nfsroot,fsc ip=dhcp rw

I need to use the mount option 'fsc' in order to use FS-cache functionality (the cachefilesd package.) However, when I try this I get the following error upon boot:

nfsmount: bad option 'fsc'

Why doesn't nfsmount permit this option? (It works fine when you mount manually with "mount -o fsc" after booting up.)

12.04 upgrade broke grub? (not wubi related)

I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More

Hi, A friend of mine destroyed his Nvidia RAID1 array somehow and in trying to fix it, he ended up with a non-working array.
