Hello Matthew,
No, it is not persistent, it will create a new RAMDISK at boot time.
But like in my case, I have a persistent ZIL that is mirrored, with small
changes on this script you can have a persistent ZIL.
But in my case, I have a special stuff, I have the ZIL at RAMDISK mirrored
and two different RAM and protected by battery, when I make a shutdown it
dump all information from RAMDISK to a SSD, and when I boot, it does
the opposite, create the RAMDISK and dump from SSD to RAMDISK and I just
attach it once again to the pool.
Best Regards,
