Hi Richard, guestfish shell has an ability to execute commands on the host such as !mkdir local tgz-out /remote local/remote-data.tar.gz What is the best way to restrict access to host from guestfish ? For instance, - Allow readonly access to host.. i.e., !ls is allowed but dont allow !rm or !mkdir - commands such as tgz-out, or copy-out should be able to access just /tmp, but nothing else in host filesystem Appreciate your guidance on this, Thanks Raghu

There's no way to do this at the moment, and no concept of a "restricted shell" in guestfish. How about running the guestfish command in a container or using a restrictive SELinux/AppArmor policy?
