mkdumprd: call dracut with --add-device to install the drivers needed by /boot partition automatically for FIPS
Currently, kdump doesn't work on many FIPS-enabled systems including
Azure, ESXI, Hyper, POWER and etc. When FIPS is enabled, it needs to
access /boot//.vmlinuz-xxx.hmac to verify the integrity of the kernel.
However, on those systems, /boot fails to be mounted due to a lack of
fs and block device drivers and the system just halted after failing to
verify the integrity of the kernel. For example, on Hyper-V, sd_mod, sg,
scsi_transport_fc, hv_storvsc and hv_vmbus need to be installed in order
for /boot to be mounted.
mkdumprd calls dracut with the --no-hostonly-default-device. Following
the documentation (man dracut),
--no-hostonly-default-device
Do not generate implicit host devices like root, swap, fstab, etc.
Use "--mount" or "--add-device" to explicitly add devices as needed
this patch uses "--add-device" to explicitly add the device of /boot.
Note there is already an attempt to fix it in dracut's 01fips module
i.e. via the commit 83651776 ("fips: ensure fs module for /boot is
installed"). Unfortunately it only installs the file system driver e.g.
xfs.
