Re: [gNewSense-users] gNewSense on a live flash drive with persistence

[ben]

i have done that with the following instructions, using ubuntu versions
later than 8.04.
if the instructions are not detailed enough, please ask.

in a german ubuntu forum/wiki [1] they mention a bug in 8.04 and 8.04.1
which makes a workaround necessary (described in [2]). they don't
mention whether this has been fixed in later service packs.

in case you succeed, you might want to do some modifications (e.g. mount
options) to optimize for flash memory. for me it was still painfully
slow, however, but it might have been my hardware that was crappy.

good luck
