Having -r is useful for different things : - We use that for the tests so every test installation/delete is done under a specified dir. - It's also useful when creating image for a different arch than the native one. - It's also useful for pkgbase to bootstrap a system/jail/whatever as at first you will not have something to chroot/jail on. > > Finally, pkg add has (deprecated) --relocate option: > --relocate location > Annotates the package as having been relocated to location, > which is an alternate system root.
