Re: Reiser4: Format 4.0.1: Meta(data) checksums

Scratch my previous issue, Ed. It is *not* related to your new Reiser4
software release 4.0.1 module nor reiser4progs.

My usual development environment is a modified non-systemd Debian Sid
(unstable) on a Reiser4 root partition. The kernels built won't boot
in *that* particular instance due to a least one other additional
issue:
target filesystem does not have requested /sbin/init

However, I tried one of my recently built reiser4-patched kernels into
a systemd Debian Sid -- also running on reiser4 root partition -- and
the system booted and behaved as you predicted.

Sorry about that, Ed. It's my fault for only testing in the build
environment (although I had not had an issue with reiser4 builds until
this kernel 4.x and new 4.0.1 software combination change).

I appreciate your input Milan, thank you.

I usually build a reiser4 module in Debian and make sure that
initramfs-tools are aware of it during kernel installation by editing
/etc/initramfs-tools/modules, adding directive: reiser4
Otherwise, reiser4 module will not be included in the initrd and the
system will not boot.

Thank you all.


Best Professional Regards.
