[SOLVED] Chroot Issue LFS 7.4 Stable No Such File or Directory

stoa · 12-20-2013, 12:05 PM

Hi everyone:

I'm missing something obvious here, I think.

I'm building LFS v. 7.4 on a Slackware host. All seemingly goes well until I hit section 6.7, Installation of Linux Headers. When trying to access /mnt/lfs/sources to access and tar the file, I can only access as far as /mnt - there is no /lfs/sources showing available in the chroot environment.

I thought it may have been a problem with $LFS not being defined for user root prior to chrooting, but after exiting chroot, confirming the variable, and re-chrooting, the problem persists.

Any clues as to what I am missing here? Here's my chroot environment:

Code:

root:~# env
TERM=xterm
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin
PWD=/root
PS1=\u:\w\$ 
SHLVL=1
HOME=/root
_=/tools/bin/env
OLDPWD=/etc

Any hints are appreciated, and please let me know if you need further information. Thanks.

Once you have entered the chrooted environment you cannot use $LFS any more. It isn't part of the environment (and shouldn't be).

This quote is from chapter 6.4 Entering the Chroot Environment:

Quote:

From this point on, there is no need to use the LFS variable anymore, because all work will be restricted to the LFS file system. This is because the Bash shell is told that $LFS is now the root (/) directory.

What used to be /mnt/lfs/sources ($LFS/sources) is now /sources.

Thanks, Druuna - I missed the (obvious) significance of the statement "This is because the Bash shell is told that $LFS is now the root (/) directory." Although, I still can't pull out of the chroot command exactly how that transfer occurred.

Thanks again.

In chapter 5 you build a temporary, self contained, working environment needed to build LFS and in chapter 6 you build the actual LFS environment (as explained in chapter 1.1. How to Build an LFS System).

Simplified the chroot command starts a contained ("jailed") environment, which can be found at $LFS (/mnt/lfs for most people). This is the chroot "$LFS" part. The rest of the command is needed to set some initial environment settings.

BTW: Can you put up the [SOLVED] tag.

Thanks for your helpful explanation, Druuna (as usual!)

PS - I've tried marking as solved twice. I can't seem to find the "solved tag" nor the "thread tools." Sorry.

Thanks, Druuna - got it. Interesting that link is not available after entering the "reply to thread" section - which is where I was, and I would think, where most folks are when actually commenting on the solution!
