It has been approximately a decade since I made such an image. Does anyone
have a recipe for creating one with persistent storage (and possibly a
separate home filesystem, or however that should be set up on btrfs?)
AFAIK it *should* still work as documented on the old wiki page:
https://fedoraproject.org/w/index.php?title=How_to_create_and_use_Live_US...
"To include a persistent filesystem for /home, use the --home-size-mb parameter. For
example:
su -c "livecd-iso-to-disk --home-size-mb 2048
Fedora-Workstation-Live-x86_64-34-1.1.iso /dev/sdX"
This will create a 2 GiB filesystem that will be mounted as /home each
time the stick is booted, allowing you to preserve data in /home across
boots.
To enable 'data persistence' support - so changes you make to the
entire live environment will persist across boots - add the --overlay-
size-mb parameter to add a persistent data storage area to the target
stick. For example:
su -c "livecd-iso-to-disk --overlay-size-mb 2048
Fedora-Workstation-Live-x86_64-34-1.1.iso /dev/sdX"
where 2048 is the desired size (in megabytes) of the overlay. The
livecd-iso-to-disk tool will not accept an overlay size value greater
than 4095 for VFAT, but for ext[234] filesystems it is only limited by
the available space."
I have no idea when is the last time anyone tested this.
