What is the difference between the buildah subcommand run and unshare? The documentation doesn’t exactly say how buildah unshare is modifying the user namespace? And I’m confused what exaclty that means.
buildah help run
Runs a specified command using the container’s root filesystem as a root filesystem, using configuration settings inherited from the container’s image or as specified using previous calls to the config command.
buildah help unshare
Runs a command in a modified user namespace.
