Subject: [PATCH] Improve error message printed for missing dependecies
|
|
|
90d067 |
|
|
|
90d067 |
The existing error message can be confusing for people that don't
|
|
|
90d067 |
know internals of blivet and libblockdev and the information what
|
|
|
90d067 |
is actually broken or not installed on the system is missing
|
|
|
90d067 |
completely. Example for LVM VDO with missing kvdo module:
|
|
|
90d067 |
|
|
|
90d067 |
Before:
|
|
|
90d067 |
|
|
|
90d067 |
device type lvmvdopool requires unavailable_dependencies:
|
|
|
90d067 |
libblockdev lvm plugin (vdo technology)
|
|
|
90d067 |
|
|
|
90d067 |
After:
|
|
|
90d067 |
|
|
|
90d067 |
device type lvmvdopool requires unavailable_dependencies:
|
|
|
90d067 |
libblockdev lvm plugin (vdo technology):
|
|
|
90d067 |
libblockdev plugin lvm is loaded but some required technologies
|
|
|
90d067 |
are not available (BD_LVM_TECH_VDO: Kernel module 'kvdo' not
|
|
|
90d067 |
available)
