While I completely agree the udev is the lesser of many possibles evils when solving the device issue... it is still evil. After attempting to craft a single rule which will work for various versions of udev in various distros. I've come to the conclusion the only maintainable way to solve this issue is to split the rule from any particular configuration. This commit provides a generic 60-zpool.rules file which use a small helper util 'zpool_id' to parse a configuration file by default located in /etc/zfs/zdev.conf. The helper script maps a by-path udev name to a more friendly name of <channel><rank> for large configurations. As part of this change all of the support scripts why rely on this udev naming convention have been updated as needed. Example zdev.conf files have also been added for 3 different systems by you will always need to add one for your exact hardware. Finally, included in these changes are the proper tweaks to the build system to ensure everything still get's packaged properly in the rpms and can run in or out of tree. |

README
============================ ZFS KERNEL BUILD ============================
1) Build the SPL (Solaris Porting Layer) module which is designed to
provide many Solaris APIs in the Linux kernel which are needed
by ZFS. To build the SPL:
tar -xzf spl-x.y.z.tgz
cd spl-x.y.z
./configure --with-linux=<kernel src>
make
make check <as root>
2) Build ZFS, this port is based on build specified by the ZFS.RELEASE
file. You will need to have both the kernel and SPL source available.
To build ZFS for use as a Linux kernel module.
tar -xzf zfs-x.y.z.tgz
cd zfs-x.y.z
./configure --with-linux=<kernel src> \
--with-spl=<spl src>
make
make check <as root>
============================ ZPIOS TEST SUITE ============================
3) Provided is an in-kernel test application called zpios which can be
used to simulate a parallel IO load. It may be used as a stress
or performance test for your configuration. To simplify testing
scripts provided in the scripts/ directory which provide a few
pre-built zpool configurations and zpios test cases. By default
'make check' as root will run a simple test against several small
loopback devices created in /tmp/.
cd scripts
./zfs.sh # Load the ZFS/SPL modules
./zpios.sh -c lo-raid0.sh -t tiny -v # Tiny zpios loopback test
./zfs.sh -u # Unload the ZFS/SPL modules
