zpool_find_import_impl() in cddl/contrib/opensolaris/lib/libzfs/common/libzfs_import.c is relying on buggy realpath() behaviour. FreeBSD realpath() does not currently conform to SUS specification (see PR 128933). It returns succesfully for invalid paths for which it should return ENOENT. The code in zpool will stop working correctly when this bug is fixed: - By default zpool_find_import_impl() operates on "/dev/dsk/" directory, which on FreeBSD doesn't exist. - It begins by attempting to canonicalize this path using realpath(). This should fail with ENOENT and abort execution, but realpath() returns succesfully. - It then proceeds to replace "/dev/dsk/" with "/dev/". - Finally it opens devices from the (now correct) directory and imports them. Fix: The correct solution IMHO is to replace all instances of "/dev/dsk/" with "/dev/". However this could be undesirable wrt new code imports. Other possibilities could be to move the 'rdsk = "/dev/";' correction up so that it happens before realpath() call, or to add "errno != ENOENT" requirement before aborting with error.

^Triage: I'm sorry that this PR did not get addressed in a timely fashion. By now, the version that it was created against is long out of support. As well, many newer versions of ZFS have been imported. Please re-open if it is still a problem on a supported version.
