What data to save before rebooting LiveCD?

LiveCD is really neat when something goes wrong, you simply reboot the
machine and the entire OS comes back to life. What troubles me is all
the configuration such as PPP, Ethernet, WLAN, Users & Groups, Quotas,
Samba, Squid, Mail and application related settings are all lost
together after a reboot.

Are there anyone working on how to backup and restore such setting
information for people who loves to run LiveCD?

It's already there. Is called Just Install The Goddamned Distribution

Dunno of anyone who loves to run LiveCD? Use them mostly for
emergency case if the distro provided emergency CD isn't
available or/and to double-check hardware on an uninstalled
system. Once used Knoppix in a computer lap, there was some
strange unusable system installed on the box. Knoppix could
resolve the situation easily, giving you a nice KDE environment
allowing to work (open multiple xterms/ssh with X11Forwarding).

Never cared about saving settings, guess it's possible, depending
on whatever "LiveCD" you are running, you fail to name? Just
check the docs coming with it/online available.

I use SLAX 5.0.2 on one of my windows machines. It is a LiveCD, which can
also be loaded to ram (don't know if that is the norm with LiveCDs or
not). I use SLAX because I don't want to install anything to those
harddrives and basically, I just use the windows partitions once or twice
every couple of weeks to boot into Win2K and use a couple programs. It
seems like a waste of harddrive space, but I have another computer I just
run Slackware 10.1 on, so it is not a big deal.

Anyways, the point is, SLAX has the capability to do a "websave" of your
configurations. So, after you boot with the SLAX CD, go into whatever you
need to and make your configuration changes, you simply run websave and it
saves all these settings to a webserver. Then, when you want to reboot
back to it, there is a command on boot, that will load those settings back
in. A very nice feature and it sounds like something you might be
interested in.

I run MEPIS LiveCD (http://www.mepis.org/) which is rich in features and
have enough applications for office desktops. I have a 512MB swap space
in my hard disk drive. MEPIS uses it and improves the OS performance
substantially. I configure one of the machines to be a Samba server
creating user and group accounts, quotas, and am now thinking to setup
internet router, mail, web proxy and firewall functions. A reboot simply
will make all this settings and configurations gone, although the users'
data may be left intact. I presume saving /etc saves all the settings
but I also believe that restoring it will affect some of the system
related files. I will be glad to know if a quick howto guide is
available on what to save and what to do after saved data is restore.
