Why ?
The log could potentially contain uncommitted entries. Without the log device
there is no knowing if it did or did not. And if it did then the pool is
inconsistent state without the log device and so it can not be imported.
The cache is not persistent and so there is nothing needed from it upon a boot.
Thank you for the clear and concise reply.
Yesterday I have done some test. If I remove the stick from the USB
port, before the shutdown the PC, it don't crash but continues to
works. Then I am able to reboot the laptop without inserting the stick
with a pool that works in degraded mode.
From the end user point of view a PC should always boot, even with a
missing ZFS log device.

Maurizio
