The scanfilesfortargetuserspace actor is generalized to allow copying directories in addition to regular files. Also fallback files/directories to copy in case the original file doesn't exist can be specified.
Currently, the mdadm configuration (/etc/mdadm.conf and the alternative location and config dirs, see man mdadm.conf#Files) is explicitly set to not be included in upgrade initramfs (via --nomdadmconf dracut option). However, this might cause errors when there are md raid devices on the system. The configuration files should be compatible between RHEL 7, 8, 9. For example, if md array locations are used in fstab instead of UUIDs: $ cat /etc/mdadm.conf ARRAY /dev/md/boot level=raid1 num-devices=2 UUID=531cea9d:bcb23190:ef4a0f87:65bf90d7 ARRAY /dev/md/root level=raid1 num-devices=2 UUID=4d920d36:ac04845a:2f67ffd8:a6f7a521 $ cat /etc/fstab /dev/md/root / xfs defaults 0 0 /dev/md/boot /boot xfs defaults 0 0 In this case /boot and / can't be properly mounted, because their location is specified in mdadm.conf. Inclusion of mdadm.conf in the upgrade initramfs should fix such problems. The file existence check in the target userspace is performed by dracut. Without the --mdadmconf flag the file wouldn't be included at all since the upgrade initramfs is --nohostonly.

Currently, the mdadm configuration (

The configuration files should be compatible between RHEL 7, 8, 9.
For example, if md array locations are used in fstab instead of UUIDs:
In this case

Without the
