looks to me like zfs already provides a mechanism for this (quotas and
reservations); it's up to the sysadmin to decide on policy.
Don't want the last 10% of the pool used? Create a "ballast" zvol or
filesystem with a big reservation, and don't put anything in it..
Of course, some degree of experimentation may be necessary before you
figure out what policy makes sense for your system or site.
