And it’ll be segregated from the base system and from other containers, like toolbox installs are?
Exactly. It's even possible to segregate it beyond what Toolbx has been able to do (at least since the last time I checked) in that you can define another folder/directory as your HOME directory within the distrobox.
Glad to be of help 💙 ! Feel free to inquire if you so desire 😉 .
