Fixed In Version:	device-mapper-multipath-0.8.4-29.el8	Doc Type:	Bug Fix
Doc Text:	Cause: When multipath is configured with "find_multipaths smart" (which it is when booting into anaconda) and a new storage device appears, it starts a systemd timer to wait for another path to the device to appear. If this timer expires while the initramfs is cleaning up to pivot to the regular filesystem during boot, it will restart multipathd, which will stop systemd from cleaning up the initramfs. Consequence: systems can hang booting into anaconda during installation, if storage devices appear late enough in the initramfs portion of the bootup. Fix: The systemd timers now conflict with initramfs cleanup, so they will automatically get stopped when the system cleans up to pivot to the regular file system. They also no longer restart multipathd if it has stopped running Result: Systems no longer hang while booting into anaconda for installation.	Story Points:	---
