Hi,

ls -l /dev/null

I'm surprised by that. Google found similar error messages where a
*user* could not do things because /dev itself had the wrong
permissions (ls -ld /dev in chroot). But you should be root here in
chroot, so perms for group and other are irrelevant.
And you bound the host's /dev in 6.2.2, didn't you ?
Oh, that must be it. I did section 6.2.2 but then I shut down
my computer and later resumed. I'm sorry. I should have known that
would be a problem. It doesn't preserve mounted stuff for the next terminal
session.
Anyway, I did that section again and it works now!
Thank you very much!
which is correct. So that can't be the problem. The FAQ
(http://www.linuxfromscratch.org/lfs/faq.html#perm-denied) also says it can be
/etc/fstab. But I'm not sure which one. The one on the host system says:
/dev/mapper/isw_bejfhacdjf_Volume1p4 / ext4 errors=remount-ro $
/dev/mapper/isw_bejfhacdjf_Volume1p5 none swap sw 0 $
/dev/mapper/isw_bejfhacdjf_Volume1p5 none swap sw 0 $
I don't think /dev/mapper entries are the problem : if there is a
problem in the host system's fstab, it probably relates to /dev
itself. I say 'probably' because I'm not familiar with that entry
in the FAQ and I don't recall anybody mentioning permission problems
with /dev on the lists.
I don't know if there is a problem there. On the LFS partition, /etc/fstab
doesn't exist. Is that a problem?
No, not at this stage - you have barely started building the final
LFS system. And since you didn't comment on my previous replies
that /mnt/lfs should be its own filesystem, I still doubt that you
will be able to boot your new system when you complete it. I hope
I'm wrong on that.
I'm building LFS in its own filesystem. For some reason my distro
mounts filesystems in media/username hence /media/isaac/LFS.
