Yo don't need anywhere near that much flash for a smoothwall, unless you're
planning to run Squid out of flash. Here's a df output from a diskful smoothie
Filesystem Type Size Used Avail Use% Mounted on
/dev/harddisk4 ext3 7.0G 4.1G 2.9G 59% /

/dev/harddisk3 ext3 510M 73M 414M 19% /var/log
Of the 4.1G in /, 4.0G is /var/squid and /var/log usage is:

Just had a look on the above smoothie : /etc & /tmp should nearly cover it
(besides /var, of course)

Make guessstimates from the above.

No, as long as you have sufficient RAM. I've 384M on that box, and 180M or so
is used for buffer/cache - so 256M would be enough, even WITH squid.

Yes, yes you will - a smoothie keeps a LOT of system data in /var. Best mount
/var/log on the RAMdisk.

Is that flash though? I'm pretty sure that the 4GB muvo uses the same tiny
hard disk as the iPod mini. Mind you from the noise POV it probably hardly
matters - I imagine those disks are rather quiet.
