Here's a sort-of relevant question: does anyone have pointers on how to optimally configure a
very old low memory laptop (say 100 MB) for use with Linux, using a CF disk or USB thumb drive
as the main 'disk'?  The hard drive has gone and I like the idea of a flash-based laptop at
almost no cost.  The laptop runs Linux fine already, but I want better performance, stability
and flash lifetime.

There are some flash-optimised Linux distros such as Puppy and Damn Small Linux (DSL), but
there's very little guidance on how best to set them up - should you use a large or small RAM
disk, how much swap should you use, etc.  Also, given the state of consumer flash devices and
their FTLs, is it best to do a 'frugal install' (install a loop filesystem, usually squashfs)
to the flash device, and save all state into a separate 'current state' loop FS, which is what
Puppy does, or simply back it up into a tarball, which is what DSL does.

There's a huge amount of expertise in setting up Linux/Unix for hard drive based systems, but
the details of setting it up for flash is rather thin on the ground, at least outside the
embedded device industry.

Flash-based linux

look up 'how to install ubuntu on the eeepc' (I did this on my eeepc) and then you have all 
the tips like 'swappiness to zero', 'noatime nodiratime', etc etc...
