Thanks for the insightful suggestions Sam.
I will definitely try some of them. I already have breakpoints
in my shutdown script and several options to pause until a key is
pressed. Currently all that my new /sbin/init script does is
touch a file and then endlessly sleep. I may need to change
I haven't forgotten about this. I had been statically linking BB
to glibc because that was easy. I'm now struggling with
buildroot to create a BB that is statically linked to uclibc.
Maybe this has been the root of the problem all along. So far
I've been able to build BB but it just segfaults

Ok thats easy, but glibc need additional files in your chroot/initramfs
to enable locale support (some files from /usr/share/locale - and maybe

Thanks Laurent, I'm learning a lot. It is refreshing to have
someone to talk with about this stuff but I'm going to have to
wrap this up soon. It feels like I'm spawning children on this
list faster than I can kill them off. I will certainly read any
replies (at least) and I might come back to

Hi James !
After some experimentation I finally got buildroot to create a
working busybox based on uclibc. I enabled wchar but disabled
all locale stuff in the uclibc config.
How shall your final BB manage UTF if you disable locale stuff in the
lib. Looks like you are building your BB the

Ah, I'm sorry, I hadn't realized you were not the OP, and I have

just trying to shut it down.
Well a shutdown isn't really something I've mastered. I've always
considered it was
Don't forgot umount -fl which pretends to unmount now but actually does it
as soon as all files are closed.
Not sure right now if busybox supports it.

Hi James,
a quick response ahead, for interest, have not looked into details of
your message. Have you ever tried:
export LANG=en_US.UTF-8

This shall count characters, not bytes (Works for me in 1.21.1). This
sed hack indeed failed on my try!

Yes! That works with both glibc and uclibc in the chroot and in
the initrd. Thank you!
I didn't know about the -m option to wc. I had ASSumed -c was
for counting characters. My bad.
