Subject: [PATCH] Improve error message printed for missing dependecies
The existing error message can be confusing for people that don't
know internals of blivet and libblockdev and the information what
is actually broken or not installed on the system is missing
completely. Example for LVM VDO with missing kvdo module:
Before:
device type lvmvdopool requires unavailable_dependencies:
libblockdev lvm plugin (vdo technology)
After:
device type lvmvdopool requires unavailable_dependencies:
libblockdev lvm plugin (vdo technology):
libblockdev plugin lvm is loaded but some required technologies
are not available (BD_LVM_TECH_VDO: Kernel module 'kvdo' not
available)

Subject: [PATCH] Use bigger chunk size for thinpools bigger than ~15.88 TiB
With our default chunk size of 64 KiB we cannot create bigger
thin pools than 15.88 TiB. Unfortunately we need to specify chunk
size to be able to calculate thin metadata properly so we can't
simply leave this to LVM to determine the correct chunk size.

Subject: [PATCH] iscsi: Replace all log_exception_info calls with log.info
We don't get any useful information from the exception, it's
always the same traceback from a failed DBus call and we only use
these when a called failed because firmware ISCSI is not supported.
The resulting log message also looks like a failure with the
traceback logged and not just as a debug information.

Subject: [PATCH] Do not crash when changing disklabel on disks with active
devices
The _find_active_devices_on_action_disks function originally
prevented from making any changes on disks with active devices
(active LVs, mounted partitions etc.) This was changed in
b72e957d2b23444824316331ae21d1c594371e9c and the check currently
prevents only reformatting the disklabel on such disks which
should be already impossible on disks with an existing partition.
This change for the 3.4 stable branch keeps the current behaviour
where the active devices are teared down when running in installer
mode to avoid potential issues with the installer.

Subject: [PATCH 4/4] Add option to attach a newly created cache pool to
existing LV
Because we do not have action for attaching the cache pool, we
cannot schedule both adding the fast PV to the VG and attaching
the cache pool to existing LV. This hack allows to schedule the
attach to happen after the cache pool is created.

Subject: [PATCH 1/8] Fix removing zFCP SCSI devices
Values parsed from /proc/scsi/scsi were not correctly used to assemble
paths to SCSI devices.
For example:
/sys/bus/scsi/devices/0:0:00:00/
was incorrectly accessed instead of:
/sys/bus/scsi/devices/0:0:0:0/
Switch to a more reliable way of listing the available SCSI devices.
