This script was added to provide a simple way to check that zpool
layers correctly on all the standard linux block device types.
It's still a little fragile if there a hiccup in say the md or
lvm tool chain but aside from that it works well.
The 'make check' target now also calls this script in a safe mode
which only operates on files and loopback devices. To check other
block devices types is must be explicitly run by hand because it
will overwrite various block devices.
Pass an alternate location via module option for the zpool.cache file
used by the kernel. This allows us to write in-tree tests which do
not modify any out-of-tree files we do not own. This is just standard
good behavior for any test suite.
Additionally, refine the existing test case to explicity use the cache
file when looking for pools to import. And add a second test cache
which is forced to probe the disks for available pools to import.
This is an initial script for validation of zfs/zpool configuration.
For now there is only one test here to ensure that /etc/zfs/zpool.cache
is being updated properly from the kernel module. Additional tests
should be added, I believe Richardo said there was an existing test
suite out there which validated the behavior of many zpool/zfs commands.
It would be nice to add that as appropriate.
This change extends the existing in-tree test infrastructure such
that it can also be run as part of a the installed package. This
simplifies testing on multiple systems and is generally all around
useful. The scripts may still be run in-tree and will use the
in-tree build products as long as .script-config exists.

Modern kernel build systems at least post 2.6.16 will set this properly
so we should not. In fact post 2.6.28 the include headers have moved
under arch so the guess we make here is completely wrong. Letting
the kernel build system set this ensure it will be correct. Also
drop the ulimit from the Makefile which, not surprisingly, turns out
to be very non-portable. If your expecting failures set the ulimit
in your shell before kicking off the test suite.
