slitaz-boot-scripts 405 sed still broken
Thanks, Aleksej, I just read your mail - yes, it will not work
and we need to change / to \/ in $root value before:
something, like this:
[c]newvariable=$(echo $root | sed 's|/|\\/|g') [/c]&&
sed "/$newvariable/!d"
instead of
sed "/$root/!d"

cp -a /init /init.patched
sed -i 's/got modprobe/busybox blkid\n&/' /init.patched
exec /init.patched

You may need a kernel module to see sdb. In this case, append modprobe=themodule in cmdline
