(the space they take up is about the same we need for persistent
USB workspace & lose in file system overheads, so IMO they dove
tail nicely)

One thing I've been considering is dropping MB-System from the
official build to save us ~400mb. The Poseidon LiveDVD already
ships it; it still has no support for shared libraries so the
binaries are huge; while interesting to me & ties in nicely with
a few other projects, it's non-OSGeo so doesn't have the same
clout when push comes to shove.

But first I want to get the build script working with Lucid. :)

I expect the regular LiveDVD installed to a USB stick from the
Apps-> System -> Create USB Startup Disk menu will be the same,
the smaller ISO just saves you some downloading?

I have only installed the vanilla Karmic, and (as of yesterday)
Lucid xUbuntu 700mb ISO from a CD onto a 4gb USB stick to test/
develop the build scripts individually. I've never tested our
final product but I see no reason why it wouldn't work. Expect
to run out of space quickly though, rather than "perpetual" I
see it more as "persistent for a month or two". See the Quick
Start Guide on the wiki for details.

I'll prepare a list of pre-installed packages for Lucid's xubuntu
(sorted by size) at some point & post it to the ticket for this.
Probably better to sort by package size not installed size as
the filesystem is compressed.
