For the technically curious, here is a summary of all of the files that are different between v2-final and the current v3-alpha5 Empeg/RioCar software releases (car2-consumer). Lines preceeded by '-' are from v2-final, and those with '+' are for v3-alpha5. Each line shows the file pathname, and its size in bytes.

Cheers.

Hm. The temptation to make separate directories for 2.0 and 3.0a(3,5) and make hijack remap things on open crossed my mind again. Maybe tomorrow.

The interesting thing is that such a "chooser" could easily be done as a userspace app from EXEC -- with a front panel menu & timeout..
EDIT:
I'm releasing a new "upgrader" shortly, with a --extract option to extract the .upgrade files into the current working directory. Under Linux, one can then do this:

mkdir t ; mount _dev_hda5 t -oloop; cd t; ls -l

Hm. There was a reason I didn't want to go that way. I wonder what it was...

Well, it will involve remounting the filesystem r/w briefly to change the symlink (or rename a directory), but only if the user selects a different option than the current setup. Just use the "nocheck" option when doing the remount so that it is instantaneous, as in:

mount / -oremount,rw,nocheck
rm -f /empeg
ln -s /empeg-v2final /empeg
mount / -oremount,ro

Of course, this whole thing could just be a shell script like the above, invoked on demand from a Hijack menu option once I fix the EXEC stuff (Real Soon Now.. maybe even this weekend, since it's too bloody cold out to play hockey).

Cheers
