# because in LAYOUT_XFS_OPT_DIR they are still listed with
# original name and copy to LAYOUT_XFS_OPT_DIR_RESTORE could overwrite
# XFS configs already migrated.
# e.g. with following disk mapping situation:
# /dev/sda2 => /dev/sdb2
# /dev/sdb2 => /dev/sda2
# Files in LAYOUT_XFS_OPT_DIR_RESTORE would be overwritten by XFS configs with
# wrong names.
# tar is used to take advantage of its exclude feature.
