As a Silverblue user I have found myself depending on Toolbox containers a lot of late - and I have also busted some. So I have started using a workflow to backup/restore and move these containers. Not sure if documentation on this kind of thing belongs in the magazine or is better in a discussion post? Also not sure of I am using the optimal method (definitely not claiming expertise)- but it does work. I have searched around for Toolbox specific information on creating backups and have not been able to find much information at all - which can be frustrating when you break them as often as I do.
The article would discuss briefly what Toolboxes are, some examples of when they can be handy and then explore using a sequence of toolbox and Podman commands to first commit and then save a Toolbox to an container image in an archive file. Followed by restoring the image and then creating a Toolbox container from it on the same or another machine.
