#* the --overlay-size-mb NNN option creates space for persistence of changes on the disk; otherwise, a liveOS disk is read-only.

#* the --home-size-mb NNN option creates space for saving the /home/liveuser folder if you want to update the OS image while keeping the user files. In this case, skip the new disk creation and parted steps and leave out the --home-size-mb NNN option at this step and continue on. <s>(This option causes login problems on VirtualBox with the liveuser account and should be skipped for now.)</s>
#* the --home-size-mb NNN option creates space for saving the /home/liveuser folder if you want to update the OS image while keeping the user files. (In this case, skip the new disk creation and parted steps and leave out the --home-size-mb NNN option at this step and continue on.) <s>(This option causes login problems on VirtualBox with the liveuser account and should be skipped for now.)</s>
#* the --unencrypted-home option prevents password protection and encryption on the /home/liveuser folder. This releaves the overhead on the compressed sqaushfs and should be more robust to file system failures (outside of security).
#* the --delete-home option is used to avoid an error message while requesting both a new home (with --home-size-mb) and a persistent home (with--unencrypted-home). You wouldn't use this option on an upgrade.
