Well, if a *persistent* boot is chosen, most things will be saved...
That includes files that you create or save, and configuration changes,
or updates from the update-inx script (which is kind of a separate
howto - you can find information about that in the list archives:
Those instructions also apply for a "persistent" boot, now that such a
thing is possible using inxusb...

You need to chose the persistent option from the Grub menu on boot.

Again, that should not happen as long as you choose "persistent" on
boot. If you accept the default (the first entry), then there will be
no persistence in that session. The same applies for the "To RAM"
option. Only the persistent option uses the the casper-rw partition on
the USB device to save and read settings and changes.
Perhaps I should simply make "persistent" the default, as others have

Yes, only the "persistent" option is "persistent", funnily enough :)
The "casper synching" message always appears, and is not really
relevant. So, in general you want to chose "persistent".

In simple terms, the inxusb script creates 2 partitions on the usb
The first one is labelled "INX", although that is not
essential. It contains the "casper" files, which are the same as those
on the CD. It also contains, after running the inxusb script, the grub
boot files needed to boot the device. This partition does not change
during a session.
The second partition is labelled "casper-rw". When you boot the
"persistent" option, the system looks for the "casper-rw" label and
uses that partition to save changes. If you have changes from a
previous "persistent" session, they will be read from that partition.
If that is still unclear, don't hesitate to ask for more information :)
It *is* a bit confusing at first - the essential thing is to select
"persistent" on boot unless you want a "volatile" session (one that
disappears in a metaphysical puff of smoke on shutdown or reboot).
Hope that helps... Let us know if you have any further problems. It
would also be good if you could report success, of course ;)
