Fwd: [Fedora-livecd-list] RFC- 'persistance' is on LiveCD wishlist - what does it mean?



I have used a livecd distro called devil-linux for some time.  They
have a "save-config-to-disk"  that saves much of /etc and /var to
disk.

When the distro boots up, it looks for a tar file to unwrap all of
/etc and /var from.

If you add /home to the list of directories that are save, it works for me.

Which is why I'm the one implementing it ;)

Actually, what I said was a bit confusing, and made it sound more like I was
going in the direction of what Don Vogt was saying that CentOS5-livecd did.  In
truth I really just meant doing the rootfs snapshot overlay as persistence, for
as you say full 'system persistence', just that in practice, the majority of it
would be used for my homedir.

OTOH, this is another situation of where I can see it possibly being useful
implementing both strategies, i.e. you can have the rootfs overlay on your
usbstick, and/or a specially named .tgz which will get automatically untarred to
/ upon boot if it exists.

I think I ought to be able to implement both by monday before the devel
freeze...  (he says ambitiously :)  I'm in the process of attempting to follow
the fedora8 feature proposal policy.  Right now I'm stuck at figuring out how to
make my first fedoraforum wiki page with the account I created last night.
(whenever I click the link 'create new page' it throws up an error saying 'you
are not allowed to edit this page'.  This is after logging on, on _my_ empty
user-homepage)
