Description Kairui Song 2020-11-19 09:54:19 UTC

Description of problem:
Currently dracut's 95fcoe module will always be installed, when there are any FCoE device on the machine.
But when building hostonly initramfs, only specified devices are used in initramfs, so installing the FCoE module is unnecessary.

Dracut should drop FCoE in hostonly mode when there is no hostonly FCoE device module, this is especially helpful for kdump.

How reproducible:
100%

Steps to Reproduce:
It can be reproduced with kdump:
1. Setup FCoE device.
2. Set the kdump target to a network device, and then restart kdump. 
2. Kdump will rebuild the initramfs, and fcoe dracut module is installed.

Actual results:
fcoe dracut module is installed in kdump initramfs

Expected results:
fcoe dracut module should not be installed in kdump initramfs
