Package: kexec-tools
Version: 1:2.0.3-2
Severity: whishlist
Since I switched to Systemd, /etc/init.d/kexec-load no longer works as I
expect. This is caused by /lib/lsb/init-functions being changed by
Systemd to integrate traditional LSB init scripts into how Systemd
works.
My current work-around was to juse out-comment that line:
-- /tmp/x/etc/init.d/kexec-load 2013-01-12 23:04:53.000000000 +0100

test -r /etc/default/kexec && . /etc/default/kexec
That now produces some warnings about the log_* functions being no
longer found, but otherwise works okay (for me).
I've done that because I like the easy way of just invoking
/etc/init.d/kexec-load stop
to load my next kernel after an kernel update, because that script
figures out the right name of the vmlinux and initrd files, and kernel
command line. I could do that by invoking kexec myself with the right
arguments, but I find the init script easier.
It would be nice if the init script would work again with systemd
installed or if the logic would be moved to an sbin/ script callable by
hand.
