The overlay is additional storage available to the live operating system if the operating system supports it. The USB storage device must have enough free space for the image and the overlay. +This option sets the overlay size in mebibytes (integer values only). The overlay makes persistent storage available to the live operating system, if the operating system supports it. The persistent LiveOS overlay holds image-change snapshots (using write-once, difference-tracking storage) in the /LiveOS/overlay-<device_id> file, which, *one should note*, always grows in size due to the storage mechanism. (The fraction of allocated space that has been consumed may be displayed by issuing the 'dmsetup status' command in a terminal session of a running LiveOS installation.) One way to conserve the unrecoverable, overlay file space, is to specify a persistent home folder for user files, see --home-size-mb below. The target storage device must have enough free space for the image and the overlay. A maximum <size> of 4095 MiB is permitted for vfat-formatted devices. If there is insufficient room on your device, you will be given information to help in adjusting your setti ngs. =item --home-size-mb -Sets the home directory size in megabytes. +Sets the home directory size in mebibytes (integer values only). A persistent home directory will be made in the /LiveOS/home.img filesystem image file. This file space is encrypted by default, but not compressed (one may bypass encryption with the --unencrypted-home installation option). Files in this home folder may be erased to recover and reuse their storage space. The target storage device must have enough free space for the image, any overlay, and the home directory. Note that the --delete-home option must also be selected to replace an existing persistent home with a new, empty one. A maximum <size> of 4095 MiB is permitted for vfat-formatted devices.
