BLFS using LFS Live CD?

AxXium · 07-22-2005, 03:55 PM

Is it possible to use the LFS-Live-CD or any other live cd to install the packages in BLFS.

The reason I'm asking is that it is a God-send to be able to copy and paste from the book. When I print out the pdf version of the book, some characters look too similar and have caused me a lot of grief while doing LFS.

Such as the number 1 & the letter l. Trust me, in the pdf version they look nearly identical as opposed to what you see right here.

This is just a thought and not a major problem other having to print the entire 938 pages of BLFS 6.0 since I can't figure out how else to see it after installing LFS until I install X in BLFS.

Any thoughts?

Yes, it's quite possible. I've installed X and such in my host (livecd) environments before.

Well, you could install links and gpm (from the BLFS book) it's easy to do this with nALFS and the BLFS profile.

But that assumes you used nALFS to install LFS.

I did not use nALFS to install LFS. I did see mention of using links & gpm at the end of the LFS book. I installed LFS 6.1 and am waiting for the companion BLFS 6.1 to be released before I continue. That should give me enough time to decide on which strategy I will use. I think that the link & gpm will be the best bet.

Thanks!

I went back to the LFS 6.1 book and read the following.

Chapter 6 Section 3

Code:

It is important that all the commands throughout the remainder of this chapter and the following chapters are run
from within the chroot environment. If you leave this environment for any reason (rebooting for example),
remember to first mount the proc and devpts file systems (discussed in the previous section) and enter
chroot again before continuing with the installations.

and I put together what I think may be the way to mount the LFS system, assume root & install software while in a live cd enviornment until X and a window manager is installed.

Tell me if this is how you did it kjordan

Code:

Step 1.

# mkdir -p $LFS/{proc,sys}


Step 2.

# mount -t proc proc $LFS/proc

Step 3.

# mount -f -t devpts -o gid=4,mode=620 devpts $LFS/dev/pts

Step 4.

# chroot "$LFS" /tools/bin/env -i \
    HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
    /tools/bin/bash --login +h

Step 5.

# exec /tools/bin/bash --login +h

Step 6.

# mount -n -t tmpfs none /dev

Step 7.

# mknod -m 622 /dev/console c 5 1 \
  mknod -m 666 /dev/null c 1 3 \
  mknod -m 666 /dev/zero c 1 5 \
  mknod -m 666 /dev/ptmx c 5 2 \
  mknod -m 666 /dev/tty c 5 0 \
  mknod -m 444 /dev/random c 1 8 \
  mknod -m 444 /dev/urandom c 1 9 \
  chown root:tty /dev/{console,ptmx,tty}


Step 8.

# ln -s /proc/self/fd /dev/fd \
  ln -s /proc/self/fd/0 /dev/stdin \
  ln -s /proc/self/fd/1 /dev/stdout \
  ln -s /proc/self/fd/2 /dev/stderr\ 
  ln -s /proc/kcore /dev/core \
  mkdir /dev/pts \
  mkdir /dev/shm

Step 9.

# mount -t devpts -o gid=4,mode=620 none /dev/pts \
  mount -t tmpfs none /dev/shm

Let me know if this is correct or if there is a short between the chair and the keyboard.

Thanks!

If you're able to get past Chapter 6 in LFS (which you're going to have to to get to installing X), then most of those steps aren't need.

Since tools will no longer be needed, you'll be using the chroot found at the end of Chapter 6
chroot "$LFS" /usr/bin/env -i \
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
/bin/bash --login

Then do
/sbin/udevstart

and since you should have an fstab completed (if you finished Chapter 7), do
mount /dev/pts
mount /dev/shm
mount /proc
mount /sys
and they should be mounted as they need to. I never really exited my chroot environment from Chapter 6, so I'm guessing that these steps are correct. They do seem like what would need to be done though to get the environment you need (since this is basically what would be done at boot).

It seems to me (and I have not done LFS yet, want to) that once you get through LFS and got to a bash prompt with a solo reboot, the live cd functionality is already done, you could burn a cd with the BLFS book and source to do this.
