I solved a long annoying boot-problem happened in the systemd-async-boot-process.
Adding a sleeptime in /lib/systemd/system/systemd-udev-settle.service
by adding ExecStartPre=/usr/bin/sleep 5
to the [Service]
-Section, gives the system 5 sec. more time to load the zfs-module and import the pool before it tries to remount root to the real directory on disk.
hdiutil convert -format UDRW -o destination.img source.iso
diskutil partitionDisk /dev/disk2 1 "Free Space" "unused" "100%"
sudo dd if=destination.img.dmg of=/dev/disk2 bs=4m
ZFS adds to every mountpoint a (hidden) subdir called .zfs
. It presents in this directory the shares
and snapshot
. Through the later one you can gain access to the fixated data from every snapshot you made. E.g. for an atomic database-backup or restore of deleted files.
Nice
