Yes. You are using /etc/reboot which is the same as calling

If you umount a ZFS FS that has some other FS's underneath it, then the
mount points for the child FS needs to be created to have those

and next time you import the pool the FS will fail to mount because your

Hi Cesare,
According to our CR 6524163, this problem was fixed in PowerPath 5.0.2,
but then the problem reoccurred.
According to the EMC PowerPath Release notes, here:

This problem is fixed in 5.2 SP1.

Crashes are abnormal conditions. If it crashes you should fix the problem to
avoid future crashes and probably you will need to clear the pool dir
hierarchy prior to import the pool.
Are you serious? I really hope that
