I agree with the concepts of; * Not enabling every feature flag on pool create * Not suggesting pool feature upgrade in zpool status Part of the issue I personally had, was that my install / recovery media tends to be a year or more behind OpenZFS / ZFSonLinux feature flag availability. So in a few cases I had to work around inability to import a root pool R/W by installing an OS on to a temporary partition, or disk. Upgrade it's ZFS and then fix the problem with the root pool. Today I don't bother upgrading my root pool beyond my install / recovery media's level of feature flags. At least until I have a newer install / recovery media.
For the new ZFS user, this can bite them. (And it bit me, even though I first used ZFS in June 2006 with Solaris 10.) My only suggestion is perhaps a new zpool create option of -D which builds the pool with the common features between FreeBSD, ZFSonLinux and Illumos. -- K. R.
