# When dracut generates the initramfs, it must refer to disks and partitions to
|
||
|
|
# be mounted in a persistent manner, to make sure the system will boot
|
||
|
|
# correctly. By default, dracut uses /dev/mapper device names.
|
||
|
|
# For example, when dracut detects multipath devices, it will use the DM-MP
|
||
|
|
# device names such as
|
||
|
|
#
|
||
|
|
# /dev/mapper/3600a098000aad73f00000a3f5a275dc8-part1
|
||
|
|
#
|
||
|
|
# This is good if the system always runs in multipath mode. But if the system is
|
||
|
|
# started without multipathing, booting with such an initramfs will fail,
|
||
|
|
# because the /dev/mapper devices will not exist. The same problem can happen
|
||
|
|
# with multipath maps and cloned SAN LUNs.
|
||
|
|
#
|
||
|
|
# To prevent this from happening, the dracut policy for addressing disks
|
||
|
|
# and partitions is changed to use /dev/disk/by-uuid device names on all
|
||
|
|
# architectures except s390/s390x, which must be by-path (bsc#915218).
