+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.
