Presently, there are a lot of special cases:
- runlevel 0 and 6 unconditionally run "script stop" if they
find a Kxxscript symlink. This may lead to trying to stop an
already stopped device if for example switching to runlevel 0/6
from runlevel 1. This can be fixed by stating the convention
that it is the responsability of scripts to check that the service
is running before killing it (or not running before starting it).
Still, we shouldn't try to stop a service if it was marked K in
the previous runlevel. And same for S files: we shouldn't try to
start a service that was marked S in the previous runlevel. Note
that changing runlevel is not a "reset": if a user has manually
changed the state of a daemon, this state will remain the same
upon changing runlevel if the S/K status of that dameon is
the same in both runlevels.
- Sxxscript symlinks in runlevel 0/6 are run as "script stop"
instead of the more intuitive "script start". This does not interact
well with LSB-tools (some scripts would need "Default-Start: S 0 6"
but then it is impossible to get correct "Required-Start" or
"Should-Start" fields). Furthermore, having a counter-intuitive
behavior is error prone. So now runlevel 0/6 will run "script
sart" for a Sxxscript.
Since the kernel can mount /dev if given the proper config
parameter, and we tell users to set this parameter when building
the kernel, this should be mentioned in the script

If run once (as it is now), the only possibility after hitting
control-D is to reboot. Note that init treats the S runlevel
differently:
when the last daemon to be run n runlevel S exits, init switches
to the default runlevel. This is not the case for other runlevels.

Change pdf generation to use 9 point fonts for monospace
sections of the book. Otherwise texy overflows, especially
in Chapter 8, Stripping.
Fix a minor spacing issue in the stripping issue.
MAke a minor grammar fix in creatingfiles.xml.
This prevents a reference to /var/run in /usr/lib/tmpfiles.d/dbus.conf,
which would cause a warning from systemd-tmpfiles.
--with-system-pid-file=/run/dbus/pid is not needed with this, but
--with-console-auth-dir and --with-system-socket are still needed.
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.
It should have been removed in 10.1, and in 11.0 there should have been
"the version of LFS has switched to a merged-/usr layout". But we just
forgot to update this all the time :).
Now adjusting.xml only serves as a historical reference, and a "snip
library" for gcc.xml. Put all relevant content into gcc.xml directly
and remove adjusting.xml. If someone needs a historical reference, he
can always get adjusting.xml in Git history.
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.
