Now that MAKEFLAGS is defined at the beginning of the scriptlet,
there is no need to pass MAKEFLAGS as an envar to the scriptlet.
But still NINJAJOBS is not defined. In most cases, when we want
to use all cores, this is not a problem. But if N_PARALLEL is
defined, it needs to be passed. Note that we also pass
MAKEFLAGS in this case, because we use the old "wrt_xxx" function,
but it is not used.
If using a new book, MAKEFLAGS is set to -j$(nproc), so that if
we want to easure timings with 4 processors and our computer has
more than that, we need to restrict the number of processors.
Jhalfs allows to do that using th cpuset cgroup controller, so that
it only restrits the make job and not the whole machine. For that
use a small scripts written by Xi Ruoyao that restarts make this
the cpuset set.
If the shell exits with an error, teardown is not run in target
chroot, which may lead to unwanted effects, such as preventing
unmounting the $BUILD_DIR. Tell make to ignore the error.
Now that devices.sh can be run even if the fs are already mounted
all the targets after mounting the virtual kernel fs can depend
on "devices". This way, if for some reason a partial build is
restarted after a reboot, the virtual kernel fs are automatically
re-mounted.
Fixes#1737
Instead of having them inside the Makefile, which implies editing
them (automatically), which is not robust if anything changes:
it got broken when a test for a mountpoint was added...
LFS/lfs.xsl does not generate correct commands for stripping if
STRIP=n. LFS/master.sh had already been corrected to not run
stripping if STRIP=n, but only for the first pass. Do this for
all passes.
The command for unmounting the kernel vfs is now
umount -Rv $LFS
So we have first to use that command in teardown (change in
kernfs.xsl). Second, since the command tries to umount
$LFS, but the Makefile is on $LFS, it fails. Ignore the
error in the Makefile (change in master.sh)
We count the number of files in lfs-commands to know whether
we have an old or a new book. But this shouldn't include the
custom-tools dir, so only count chapter*.
- Prefer SysV over Sys V in Config.in
- do not generate the package list for lfs, it is not needed anymore
- prevent an (ignored) error in LFS/master.sh
- log new files under the scriptlet name (allows to log files for the same
package from different builds)
- keep the full name in log_new_file functions (fix a undetected bug in
CLFS/HLFS)
We use the filter builtin function of make to retrieve the right
shell to use during the CHROOT phase, which is the same as the
one in CHROOT1.
Also do not assume envars exist when removing it at the beginning
of the SUDO phase.
This involves changing the way make targets are built. Specially
the make target is changed when encountering a specific file
(for example the make target becomes sudo when rencountering kernfs)
This allows more flexibility.
- take targets from scriptlet names
- neutralize some commands or bash builtins so that they are not
used even if they are in the scriptlets, if not needed
- do not set PREV in chapter 5 anymore
- Improve save and restore user, so that if the LUSER exists,
its home is saved while building temporary tools, and restored
afterwards
This is to allow root to execute ": > envars". On a non empty envars
owned by lfs, in a directory world writable with sticky bit and not owned
by lfs, this may be forbiden by the fs/protected_regular sysctl.

- add sect1info sections to packagemanager.xml.xxx + various fixes
- add templates in LFS/lfs.xsl for script start and script end:
- script start: define variables containing package information
print disk usage
unpack and change dir
- script end: print disk usage
remove build dir
- remove the corresponding operations from master.sh
