Hi,
I have a tmp directory with all files placed in:
find . -mindepth 1 -printf '%P\0' | sort -z | LANG=C bsdtar --uid 0
--gid 0 --null -cnf - -T - |\
LANG=C bsdtar --null -cf - --format=newc @- | zstd -T0 > /initrd.img
and this initrd.img I want to write into kexec without creating the initrd file.
kexec -l /vmlinuz-linux --initrd=/initrd.img --reuse-cmdline
systemctl kexec
Thanks for your help.
greetings
tpowa
