Another question on building LFS Version 20191222-systemd:
In Section "5.37. Changing Ownership" there's a Note:
"The commands in the remainder of this book must be performed while
logged in as user root and no longer as user lfs. Also, double check
that $LFS is set in root's environment."
At this point in the build process I'm logged in as user lfs, having
done so with "su - lfs" back in Section "4.3. Adding the LFS User".
I could "exit" and get back to whatever user I was, and then do
"su - root" or "su root" or perhaps something else.
How do you recommend logging in now as user root?
Sorry, I'm not fully confident that I know how a shell versus a
login shell plays in the LFS environment.
Use 'exit' to return to the previous user. You will need to change to the
root user if you are not already there in order to do some preliminary
work. Then in Section 6.4 you will enter chroot (only root can run that)
and will be the root user there. Being in chroot should be apparent from
the '(lfs chroot)' part of the prompt.
Alright, now I've gone through the LFS book looking for where the user
changes. Here's what I've found:
Up to Section 2.3 you're probably going to be your regular user name, in my
case "alan". Later you switch to "root" and "lfs".
Section 2.3.1 mentions procedures done as the root user after Section 2.4 .
All of the commands after that require you to be root, not an unprivileged
user. So presumably you would become root with "su root" not "su - root".
Right?
Section "2.3.2. Chapter 5" says that "all instructions in chapter 5 must be
done by user lfs. A su - lfs needs to be done before any task in Chapter 5."
When we get to my Section 5.37 of interest in this email, the Note says:
"The commands in the remainder of this book must be performed while
logged in as user root and no longer as user lfs. Also, double check
that $LFS is set in root's environment."
So using 'exit' will return you from user lfs to user root. This is the
answer I was looking for.
And if you somehow foul up the various "su" invocations -- which I've done
several times in past builds -- you have to do "su root" and make sure that
all the environmental variables are set properly. Right?
Actually it doesn't matter how you switch to root. The commands needed are
basic. It DOES matter that the environment variable LFS is set for the root
user.
Switching to user lfs DOES matter when switching to user lfs.
Ok, that helps clear things up for me, thank you.
Different subject: On 12/30/2019 I sent this support list an email titled
"Make and install errors with gcc-9.2.1 on Fedora ?" I'm stuck until the
questions are resolved. With the holidays, perhaps it got overlooked? Waiting
with baited breath. . .
Hmmm, I've answered (maybe not what you were expecting?):

It's odd that I got no email response on this. But the URL was useful,
thanks.
In any case, I finally got past the problem.
I suspect it had to do with my messing up by compiling various things
improperly with "su root" and/or "su - lfs", and making other mistakes.
Hard to know after so many steps and the many interruptions of daily life.
