NFS + ZFS - Base System readonly

[Philipp Vlassakakis]

Hi,

has anyone experience in mounting a base system via PXE + NFS as readonly and then mount ZFS datasets r/w on top of the base-system?

I would like to boot a basesystem (which is stored on a NFS share) via PXE and mount ZFS-Datasets on top of that, so i can rollout specific configs (hostname, services...) per Host and give user the ability to edit config files (apache, mysql...) and store data on the ZFS-disks, which will not be wiped due to a Host reboot.

Is this possible?

Thanks,
Philipp
