jhalfs, makefile restart (LFS build only)

Manuel,

   This is a first pass at a 'restart' mode for the
makefile. (please 
excuse the poor structure). I interrupted my LFS build part
way through 
the build of 066-glibc, rebooted the 'puter, entered the
jhalfs dir and 
issued  <make restart> It remounted the vfs and
restarted 066-glibc.
   It is not perfect...  your
opinion/suggestions/improvements??

   G.



restart: restart_code all


restart_code:
	if
[ -f ???-kernfs ]; then \
	 echo "Remounting the virtual filesystem"; \
	 mkdir -pv $(MOUNT_PT)/{dev,proc,sys};\
	 if [ ! -e $(MOUNT_PT)/dev/console ]; then \
	   mknod -m 600 $(MOUNT_PT)/dev/console c 5 1;\
	 fi;\
	 if [ ! -e $(MOUNT_PT)/dev/null ]; then \
	   mknod -m 666 $(MOUNT_PT)/dev/null c 1 3;\
	 fi;\
	 if !  mount -l | grep bind >/dev/null ; then \
	   mount --bind /dev $(MOUNT_PT)/dev;\
	 fi;\
	 if ! mount -l | grep "$(MOUNT_PT)/dev/pts"
>/dev/null ; then \
	   mount -vt devpts devpts $(MOUNT_PT)/dev/pts;\
	 fi;\
	 if ! mount -l | grep "$(MOUNT_PT)/dev/shm"
>/dev/null ; then \
	   mount -vt tmpfs shm $(MOUNT_PT)/dev/shm;\
	 fi;\
	 if ! mount -l | grep "$(MOUNT_PT)/proc"
>/dev/null ; then \
	   mount -vt proc proc $(MOUNT_PT)/proc;\
	 fi;\
	 if ! mount -l | grep "$(MOUNT_PT)/sys"
>/dev/null ; then \
	  mount -vt sysfs sysfs $(MOUNT_PT)/sys;\
	 fi;\
	fi;

Looks that it should to work and is a very failsafe
approach.

I can't think on a  better way at this moment.

The code is in the jhalfs SVN trunk version. 

How to add it to restart and old stopped build depend on how
old that build is 
and requires to know very well how to jhalfs and the
Makefile works to can 
fix possible issues.

I reccomend you to start a new build from scratch using
current jhalfs SVN 
trunk code.

I do it
I start LFS process

I stop process.......reboot

then I run:

mkdir /mnt/build_dir
mount /dev/hdxx /mnt/build_dir
export SRC_ARCHIVE=/mnt/build_dir/......
export LFS=/mnt/build_dir
cd /mnt/build_dir/jhalfs
ln -s /mnt/build_dir/tools /tools
make restart

and .....

it continue LFS building....

OK good

it finish


thankyou

p.s.
where can I found documentation to build BLSF in automated
way ?
