That sounds like a very attractive possibility. The concept is simple enough - create a snapshot before doing anything hazardous, and provide a mechanism for mounting a specific snapshot at boot time. Here's a link to the Fedora proposal... https://fedoraproject.org/wiki/Features/SystemRollbackWithBtrfs It seems this feature is partially implemented in F13 - the automatic snapshots are enabled, though the UI is missing. On an LFS, there's no automatic update process, so I figure I'd just create periodic snapshots, say a weekly cron job, or maybe just manually. And then configure an entry in grub to boot from the previous snapshot. The concept is simple enough, I just haven't had a good chance to try it out...

Re: live and learn
Thanks for all your tips, advice, lectures, opinions, etc. Very positive community. I think I'm going to enjoy my LFS experience. I can definitely say that despite the obvious lesson for me here (think before [Enter]), mistakes aren't necessarily a completely negative thing, as you can learn a great deal in response to your mistakes. This thread proves it. Now if one makes the same mistake more than once then that's a differnt story. :-) So until my next learning experience, Ciao for now. /carl h. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Depends on how long between same mistakes. Be sure to do
as few activities as you can with root authorization. Don't
log in as root. Use sudo or su - to change to root temporarily,
and then immediately exit back. Use a red colored prompt
when running with root authorization.
So until my next learning experience, Ciao for now.

I'm not seeing a /tools/bin/ld. Looks like you've missed a step or two,
either in Binutils Pass 2 or in the Toolchain Adjustment (or both). It
might be possible to mv /tools/bin/ld{-old,}, exit chroot, chown -R lfs
$LFS/tools, and redo Binutils Pass 2, then redo the toolchain adjustment
for ld...though I'd prefer just to go back to the beginning so you're
more certain that it would actually work...
