25# By default, a verbatim import of all pools is performed at boot based on the
26# contents of the default zpool cache file.  The contents of the cache are
27# managed automatically by the 'zpool import' and 'zpool export' commands.
28#
29# By setting this to 'yes', the system will instead search all devices for
30# pools and attempt to import them all at boot, even those that have been
31# exported.  Under this mode, the search path can be controlled by the
32# ZPOOL_IMPORT_PATH variable and a list of pools that should not be imported
33# can be listed in the ZFS_POOL_EXCEPTIONS variable.
34#
35# Note that importing all visible pools may include pools that you don't
36# expect, such as those on removable devices and SANs, and those pools may
37# proceed to mount themselves in places you do not want them to.  The results
38# can be unpredictable and possibly dangerous.  Only enable this option if you
39# understand this risk and have complete physical control over your system and
40# SAN to prevent the insertion of malicious pools.
