I can see es planing this to a noob! lol
Here's the objective; To make a simple way for a new fledgling to put his /
her system back to how it was, say...yesterday! Before they downloaded a
bunch of updates and broke stuff by bad config changes and what not!
On the particular distro I'm using, it comes as a live cd and it's really a
dead simple task. So easy, even I can't screw it up after 3 or 4 attempts!
:) It has a ~remaster-me~ script as a menu item in KDE. So long as you dont
grow your system beyond the size "squashable" by squashfs (about 4GB down to
750MB IIRC) AND, you remember, AND actually act on that memory to make a new
bootable snapshot of that system, your in fine shape. Even then, you can
make a Live DVD if you have the hardware to do so. It doesnt get too much
simpler than this and yet, there are pitfalls. If your /tmp directory or
swap partition are too small, it falls over. If you partitioned separately
and placed /home on another partition, it wont work at all.
A suggestion made to me from a collegue was to look at a system of
subversion; where any config changes cause the changed files to be copied to
a local repository of sorts and a tracking system that can have
"checkpoints" created so that you could theoretically step back in time to
any point of your changes without wiping and re-installing your entire
system. It's odd with Linux...that the things each user considers difficult,
is directly related to their depth of knowledge. I suppose most things are
like that really but I do know this...when trying to attract fresh blood in
the audio world, it's a daunting thought to try and make them understand
"Oh, you will have to completely re-install 2 or 3 times before you get the
hang of it." :)
Curious what everyone thinks about the subversion concept. It makes some
sense to me, but then I'm an idiot! :)
