IMPROVEMENT: not presuming the path of the zfspool

[JOduMonT]

1st, thanks for your scripts, they are wonderful!

Maybe something to consider as an improvement,
it is a tiny detail but for me is somewhat awkward that a script presume; in that case
the path of my zfspool.
To give a concrete example:
I have a different pool; and as I understand it is a personal choice, I prefer having my point in /mnt
zfs set mountpoint=/mnt/ssd ssd

but when I execute one of your script, it presumes my zfspool should be /ssd and not /mnt/ssd

So, I have to put a curveball in my taste if I want to use your script ;)
Otherwise, everything is running perfectly so far.
