[SOLVED] If i want to use live iso again, after rebooted LFS

whjeon · 03-24-2018, 01:47 AM

Dear Mentors!

If I want to re-use live-iso's GUI for convenience after successfully rebooted shiny new LFS, is it OK to follow instructions already used to chroot into /mnt/lfs?(the process like mount virtual filesystem, mount the filesystem, and chroot with the specific command indicated in the book?link)

Are there any other things I should aware of?

Thanks for another help!

Some people do the early stages of BLFS in chroot, at least until they have a working browser for reading the Book. You will need to mount everything (including virtual filesystems) exactly as described in Chapter 6 of LFS. And make sure that when you chroot, you are using /usr/bin/env and /bin/bash, not the obsolete versions in /tools.

You can compile most of BLFS in chroot. I compiled most of it from Fedora until I got a browser working in blfs. Keep in mind that /tools does not exist for a completed LFS. That command in the link will not work.

Here is what I used:

Code:

mount -v --bind /dev $LFS/dev
mount -vt devpts devpts $LFS/dev/pts -o gid=5,mode=620
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
mount -vt tmpfs tmpfs $LFS/run

Code:

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

    /bin/bash --login

Awesone! Thanks for your precious information!!

What I do is to put all the mount commands in a script ending with the chroot command itself. I keep the script in root's home directory. Then, when I want to work on the new system, I just type "~/setup_chroot".

For me, this thread is too precious. Can't believe how much this information helped me. Thanks again! REALLY! I'll do that too! I didn't think about that.
