But make sure you do it properly - if your script is like this:
# Begin my_script.sh
export LFS=/mnt/lfs
export FOO=blabla
Then simle `bash my_script.sh' won't help becouse the bash you just
ordered will fork a totally new process which will run my_script.sh, set
its own enviroment and then die. You should do: `source my_script.sh'.
What I usually do is
# mount /dev/device /mnt/someplace
# cd /mnt/someplace
# ./restart_script

There is a hint written about that. I used the same CD-ROM you
are using to build 6.5 successfully a couple of times.
I don't recall the entire URL, but I have a copy of that, and
the file name is
stages-stop-and-resume.txt
I'm sure if you look in the hints section of the web site you
can find it. If you have troubles, then I can shoot you a copy
via separate e-mail.
First, you can't really just shutdown whenever you like. You
have to let any given build complete. You don't have to do
an install, however.
Second, when all activity has stopped, and a build has successfully
completed, you certainly can shut down. I *highly* recommend that
you write down exactly what you were doing, and what the next step
needs to be, on a piece of paper, and conserve it with the machine
where it will not get lost, or put it into a text file on the
file system you need to mount. It's surprising how long you can
put a build aside, thinking you'll be back at it next day, and
then find out two weeks later, when you finally get back to it,
that you can't remember just where you were.
Third, in order to restart, you have to do some maintenance stuff.
You have to mount your partitions, and set up some shell variables,
like $LFS. This initial setup can be put into a little shell script
in the top level of your mounted build file system. Later, you'll
want to add another to enter the chroot environment, and then another
which can be run inside the chroot to set up what you need. The
scripts are not necessary, but are very helpful.
That said, it is easier not to have to reboot, if you can avoid it.

If I understand you right, you want to shutdown the computer while installing LFS and resume the installation later? There is a hint for this here: http://www.linuxfromscratch.org/hints/downloads/files/stages-stop-and-resume.txt It is kind of old, but the basics should still apply for newer versions of the book. However, I have lost track of all the changes that were made in the past months, so I would not entirely rely on the information. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

If you're following the book properly, you are losing nothing.
You do have to go through the setup again, and remount your
file system(s). Are you pretty much UNIX savvy, and understand
the concept of a mount and what it does?

As I have understood it, you booted the livecd, made the preparations, built, stoped, rebooted (or whatev) and now you can't resume. It's simple - the root filesystem of the livecd lives in RAM and goes away with the power. What's on the HDD (/mnt/lfs) does not, ofcourse. So, when you boot the livecd, make a new user and build, then all that happens above /mnt/lfs is volatile. Upon rebooting, you just have to redo ALL the enviroment setting-up. Mike and others have already explained the details. The scripts they mention should be put somewhere under /mnt/lfs, so that they themselves are not in volatile memmory. Upon rebooting, run them. But make sure you do it properly - if your script is like this: # Begin my_script.sh export LFS=/mnt/lfs export FOO=blabla Then simle `bash my_script.sh' won't help becouse the bash you just ordered will fork a totally new process which will run my_script.sh, set its own enviroment and then die.
