All PXE boot does it bring the kernel in. Once the actually kernel that
is going to be used is loaded, the PXE bootloader is gone.
I'm not sure how NFS handles caching. Programs that are running have
their active parts sitting in memory. A peek at 'vmstat' on my running
epia mythfrontend shows:
procs -----------memory---------- ---swap-- -----io---- --system--
----cpu----
r b swpd free buff cache si so bi bo in cs us sy
id wa
0 0 0 185596 0 23460 0 0 98 0 151 138 7 0
92 0
So, there's some caching going on.
It's a good idea to use a ramdisk for /tmp.
I have in /etc/fstab:
tmpfs /tmp tmpfs defaults,nosuid,size=4M,mode=777 0 0
