Some host create /dev/shm as a tmpfs. Some have is as
a symlink to a location in another directory. This
change handles both cases.
The change to the sysV bootscripts now creates /dev/shm
as a separate tmpfs from /run. This makes LFS sysV and
systemd versions treat /dev/shm the same.
Don't emphasis "static library" at all, to prevent anyone from thinking
"I need to use static libraries so I'll keep these .la files". And warn
that .la files are known to break BLFS packages.
It works out of box with glibc-2.35. I think this issue is already
fixed at glibc side, by the commit:

regex: copy back from Gnulib
Copy regex-related files back from Gnulib, to fix a problem with
static checking of regex calls noted by Martin Sebor. This merges the
following changes:
* New macro __attribute_nonnull__ in misc/sys/cdefs.h, for use later
when copying other files back from Gnulib.
... ... (unrelated things trimmed)
Q: Why not just move the note after the creation of root-level
directories?
A: Root-level directories may be already created as well: if a
root-level directory is a mount point it should have been created in
section "Mounting the New Partition".

This is to match the "new" way of device handling with devtmpfs (already
widely used in recent ten years).
In a normal booting process, the kernel mounts devtmpfs at very early
stage. So the static nodes won't be used at all. The only situation
where the kernel can't mount devtmpfs is "/dev is missing", but it means
those two static nodes can't exist anyway, and a normal LFS system
(without initramfs) won't boot in such a bad situation.
Removing static /dev/console and /dev/null may cause trouble for those
people or scripts chroot into LFS tree without mounting devtmpfs. But
entering a chroot with only console and null in /dev is already
problematic. For a reference, If a systemd service is started with
PrivateDevices=true, systemd will create 18 nodes and symlinks to form a
"minimal" /dev.
This is the issue preventing us from cross-compiling libstdc++ in
Chapter 6. By fixing this issue we can remove a seperate pass 2 for
libstdc++ and simplify the instruction.
The upstream fix will be released in 11.3 and 12.0, so we can remove the
first sed upgrading gcc next time.
In the new cross-compilation approach, the $PATH in chroot does not
contain '/tools/bin'. So "+h" is useless in chroot as the newly
installed tools always replace the temporary counterpart at the same
location.
"+h" in chapter4/settingenviron.xml is kept deliberately. Currently
$LFS/tools/bin only contains programs prefixed with
"x86_64-lfs-linux-gnu-", and it's highly unlikely that any distro will
ever ship a program named with such prefix. So it may seems that we can
remove this "+h" as well. However, the situation may change in future
and we can take this oppertunity to teach the advantage and disvantage
of bash hash feature.
Update to gawk-5.1.1.

Change /bin to /usr/bin in passwd, and revisedchroot.
Fix systemd for new meson.
Renamed chapter07/stripping.xml to chapter07/cleanup.xml
Removed stripping from the end of Chapter 7. We suggest a
10 GB or larger partition in Section 2.4 - Creating a New Partition
and the space used before cleaning up is only 3 GB. Stripping
would free up about 300 MB more, but these files will soon be
overwritten anyway.
Remove /tools here to save about 1 GB.
General reorginization and rewording.
Chapter 8 stripping still needs to be updated after this change.
In chapter 7 we do not need to unmount file systems to strip binaries.
Move unmounting to the backup/restore sections.
Also make sure the stripping commands are valid.
The behavior of --strip-unneeded and --strip-all are same for
executables and shared libraries. For static libraries,
--strip-unneeded keeps the symbols needed for relocation processing so
it won't break static archives.
