I ended up starting this wiki page, https://fedoraproject.org/wiki/LiveOS_image in order to collect some of this information from various sources for easier documentation and reference. Much of it is written in a very terse style best for slow and careful reading. The livecd-iso-to-disk manual page is also useful and often overlooked, https://github.com/rhinstaller/livecd-tools/blob/master/docs/livecd-iso-to-disk.pod For example, it documents a swap-size-mb <size> option. --Fred
