If I've parsed your mail correctly, you are updating glibc on a
completed system.
Right. Completed, at least, to the point where KDE etc. can be
installed.
If I've misparsed that, I'm sure I'll find out
when I start my next test build.
Very few people here update glibc in a running LFS system. Unlike
binary distros, we don't ship a new build of glibc when the kernel
headers change (or, indeed, at all - we don't ship any binaries).
That makes sense to me for the stable versions of LFS, but I
thought the purpose of the development versions was for someone
like me to install new packages as they come along.
For the mot part, yes. glibc is probably the biggest exception
because everything relies on it.
Ok. But I'm not clear about what to do with kernel updates. Should I
do as I did?: Do the "make headers" thing for each new kernel
version, then recompile glibc against that? And then compile the new
kernel? That seemed to work ok as I updated from linux-5.4.6 to 5.4.8
to 5.4.13. Or should I refrain from doing the "make headers" thing
for the new kernel, leave glbic alone, and just compile the new kernel?
Just do the instructions in LFS Section 8.3.
make mrproper
make menuconfig
make
make modules_install
cp files to /boot
edit/update /boot/grub/grub.cfg
reboot
So then, as far as linux-5.5.0 goes, is it ok to install it? Or should I
stay with what's running now: linux-5.4.13?
An update to 5.5 should be fine. You can always boot back to the
previous version.
Here is a hint:
cp /boot/config-<version> .
make oldconfig
Answer the questions. Don't enable anything new unless you have a
specific reason.
make
...
If you need an initrd that depends on the kernel, you will need to
rebuild that. I have an initrd that only updates the cpu microcode,
but that does not depend on the kernel and can be used for multiple
kernels.
Can you point me to some documentation about that? I don't know anything
about such an animal.
