+* archisolabel= Set the filesystem label where archiso files reside.
+ Default: (unset)
+* archisodevice= Set the device node where archiso medium is located.
+ Default: "/dev/disk/by-label/${archisolabel}"
+* archisobasedir= Set the base directory where all files reside.
+ Default: "arch"
+* aitab= Set the path for "aitab" file.

+ Default: (unset)
+* cowspace_size= Set the size of tmpfs /cowspace. This space is used for
+ Copy-On-Write files of dm-snapshot.
+ (directory not visible outside initramfs)
+ Size is in bytes (suffix with "k", "m" and "g") or
+ in percentage of available RAM.
+ Default: "75%"
+* copytoram_size= Set the size of tmpfs /cowpytoram. This space is used for

+ Size is in bytes (suffix with "k", "m" and "g") or
