Eek. Swap is *not* discardable. It could contain data (eg that email 
you started writing on another dekstop) which an application hasnt 
written out.

Further, while the data on swap might not be that terribly missed, a 
disk failure will likely kill your machine now, which makes it 
difficult for machine to write out non-discardable data...

tmpfs is even faster for /tmp (and is backed by swap).

/ on LVM? Fair enough, but if ever anything goes wrong you'll need a 
rescue disk with lvm2 tools. / directly on RAID1 is a much easier 
rescue position - you dont even need RAID support to access your 
data.

yes.

other than above, no.

that sounds like a good idea. btw, where do you live?
