#
# Verify that an assortment of known good reference pools can be imported
# using different versions of the ZoL code.
#
# By default references pools for the major ZFS implementation will be
# checked against the most recent ZoL tags and the master development branch.
# Alternate tags or branches may be verified with the '-s <src-tag> option.
# Passing the keyword "installed" will instruct the script to test whatever
# version is installed.
#
# Preferentially a reference pool is used for all tests.  However, if one
# does not exist and the pool-tag matches one of the src-tags then a new
# reference pool will be created using binaries from that source build.
# This is particularly useful when you need to test your changes before
# opening a pull request.  The keyword 'all' can be used as short hand
# refer to all available reference pools.
#
# New reference pools may be added by placing a bzip2 compressed tarball
# of the pool in the scripts/zfs-images directory and then passing
# the -p <pool-tag> option.  To increase the test coverage reference pools
# should be collected for all the major ZFS implementations.  Having these
# pools easily available is also helpful to the developers.
#
# Care should be taken to run these tests with a kernel supported by all
# the listed tags.  Otherwise build failure will cause false positives.
#
#
# EXAMPLES:
#
# The following example will verify the zfs-0.6.2 tag, the master branch,
# and the installed zfs version can correctly import the listed pools.
# Note there is no reference pool available for master and installed but
# because binaries are available one is automatically constructed.  The
# working directory is also preserved between runs (-k) preventing the
# need to rebuild from source for multiple runs.
