Subject: [PATCH] Improve error message printed for missing dependecies
585101
585101
The existing error message can be confusing for people that don't
585101
know internals of blivet and libblockdev and the information what
585101
is actually broken or not installed on the system is missing
585101
completely. Example for LVM VDO with missing kvdo module:
585101
585101
Before:
585101
585101
device type lvmvdopool requires unavailable_dependencies:
585101
libblockdev lvm plugin (vdo technology)
585101
585101
After:
585101
585101
device type lvmvdopool requires unavailable_dependencies:
585101
libblockdev lvm plugin (vdo technology):
585101
libblockdev plugin lvm is loaded but some required technologies
585101
are not available (BD_LVM_TECH_VDO: Kernel module 'kvdo' not
585101
available)
