Comment 1 for bug 1577057

What did you have rootdelay set to? I just tested again now with "rootdelay=1" as well as the useless "rootdelay=0" and invalid "rootdelay=".

Try adding "set -x" to the top of /usr/share/initramfs-tools/scripts/zfs, rebuilding the init script, and rebooting with rootdelay set. Grab a picture of the output so I can see what it's running just before it fails.
