[u-u] Live booting from USB key (.iso)

[arocker at Vex.Net]

Has anyone had any success with this?

I'm getting partial successes by thrashing about, but actually
understanding the factors involved (how the key should be partitioned,
whether to dd or cp the .iso, what filesystem type, what mode settings are
required, &c.) would probably speed up the process.

I don't want to start a hand-waving discussion, so I won't give details
unless someone has the experience.
