zed monitors ZFS events. When a zevent is posted, zed will run any
scripts that have been enabled for the corresponding zevent class.
Multiple scripts may be invoked for a given zevent. The zevent
nvpairs are passed to the scripts as environment variables.
Events are processed synchronously by the single thread, and there is
no maximum timeout for script execution. Consequently, a misbehaving
script can delay (or forever block) the processing of subsequent
zevents. Plans are to address this in future commits.
Initial scripts have been developed to log events to syslog
and send email in response to checksum/data/io errors and
resilver.finish/scrub.finish events. By default, email will only
be sent if the ZED_EMAIL variable is configured in zed.rc (which is
serving as a config file of sorts until a proper configuration file
is implemented).

Issue #2
zfs-fuse provides the same commands and man page names as ZoL.
Changing the names on either side would make each incompatible with
all existing documentation about ZFS. Providing bit identical files
is not possible due to differing codebases.

This adds systemd unit files replacing the functionality offered by
the SysV init script found in etc/init.d.
It has been developed and tested on Fedora 19, Fedora 20
and openSuSE 13.1.
Four unit files and one target are offered.
zfs-import-cache.service:
Import pools from /etc/zfs/zpool.cache. This unit will wait for
udev to settle.
zfs-import-scan.service:
Import pools by scanning /dev/disk/by-id for zvols. This unit will
only run if /etc/zfs/zpool.cache is not present. This unit will wait
for udev to settle
zfs-mount.service:
Mount ZFS native filesystems. It contains a dependency to be loaded
before local-fs.target.
zfs-share.service:
Share NFS/SMB filesystems. This unit contains a dependency that
will cause it to be restarted whenever the smb or nfs-server unit
is restarted, restoring the shares added.
zfs.target:
This target pulls in the other units in order to start ZFS. It's
the only unit that can be enabled/disabled, all other services
are static and pulled in by dependencies. It will honour zfs=off
and zfs=no options on the kernel command line.

Four new dataset properties have been added to support SELinux. They
are 'context', 'fscontext', 'defcontext' and 'rootcontext' which map
directly to the context options described in mount(8). When one of
these properties is set to something other than 'none'. That string
will be passed verbatim as a mount option for the given context when
the filesystem is mounted.
For example, if you wanted the rootcontext for a filesystem to be set
to 'system_u:object_r:fs_t' you would set the property as follows:
$ zfs set rootcontext="system_u:object_r:fs_t" storage-pool/media
This will ensure the filesystem is automatically mounted with that
rootcontext. It is equivalent to manually specifying the rootcontext
with the -o option like this:
$ zfs mount -o rootcontext=system_u:object_r:fs_t storage-pool/media
By default all four contexts are set to 'none'. Further information
on SELinux contexts is detailed in mount(8) and selinux(8) man pages.

The GNU libtool documentation states to start with a version of 0:0:0,
rather than 1:1:0. Illumos uses the name libzfs_core.so.1, so to be
consistent, we should go with 1:0:0.
http://www.gnu.org/software/libtool/manual/libtool.html#Updating-version-info
The GNU libtool documentation also provides guidence on how the version
information should be incremented. Doing this does a SONAME bump of the
libzfs and libzpool libraries. This is particularly important on Gentoo
because a SONAME bump enables portage to retain the older libraries
until any packages that link to them are rebuilt. The main example of
this is GRUB2's grub2-mkconfig, which will break unless it is rebuilt
against the new libraries.

Issue #1751
When the kmod packaging infrastructure was originally added the
dependency on the rpmfusion yum repositories was disabled. This
was done at the time in favour of getting local builds working.
Now the time has come to conditionally re-enable that functionality
so we can properly provide binary kmod packages.
./configure --with-config=srpm
make SRPM_DEFINE_KMOD='--define="repo rpmfusion"' srpm-kmod
mock rebuild zfs-kmod-x.y.z-r.el6.src.rpm
One nice benefit of finishing this work is that the generic and
fedora spl-kmod spec files can be merged again.

By adding a dkms_version conditional it's now possible to specify

yum repositories to ensure the patched version of dkms provided
by the repository is installed. The patched version of dkms

There are a number of issues with the generic kmod RPM spec in its
current state:
- The "%{__id_u}" macro seems to not be available on some systems (e.g.
Debian squeeze). It appears it has been deprecated. Use "${__id} -u"
instead.
- The way the "--with-linux=" configure option is generated in the
non-RHEL/Fedora case is completely wrong with various newline and
escaping issues (also, $kernel_version is not available in the
generator context).
The second issue made the generator shell snippet (almost) silently
fail, which under specific circumstances can result in broken builds
against the wrong kernel sources.

Commit f6fb7651a0 introduced the idea
of working builds which work correctly. However, because the zfs-kmod
depends on a specific 'spl-devel-kmod = {version}-%{release}' package
and the release component is unique the dependency is never satisfied.
This requires line was introduced to ensure the correct version of the
spl is always used. In this context only the version number is required
so the release component has been dropped to satisfy the dependency.

In order to ensure that yum-builddep pulls in all the build

Adding the 'spl-dkms = VERSION' dependency to the zfs-dkms
package ensures the spl will be installed before zfs. This
cleanly handles the initial 'yum localinstall' case.
However, this does not address the dkms rebuilds caused by
a new kernel being installed. For that we still rely on the
clunky --with-spl-timeout=<timeout> configure option which
allows the zfs compilation to be briefly delayed while the
spl components are built.

Refresh the existing RPM packaging to conform to the 'Fedora
Packaging Guidelines'. This includes adopting the kmods2
packaging standard which is used fod kmods distributed by
rpmfusion for Fedora/RHEL.
http://fedoraproject.org/wiki/Packaging:Guidelineshttp://rpmfusion.org/Packaging/KernelModules/Kmods2
While the spec files have been entirely rewritten from a
user perspective the only major changes are:
* The Fedora packages now have a build dependency on the
rpmfusion repositories. The generic kmod packages also
have a new dependency on kmodtool-1.22 but it is bundled
with the source rpm so no additional packages are needed.
* The kernel binary module packages have been renamed from
zfs-modules-* to kmod-zfs-* as specificed by kmods2.
* The is now a common kmod-zfs-devel-* package in addition
to the per-kernel devel packages. The common package
contains the development headers while the per-kernel
package contains kernel specific build products.
