Note that I don't feel any requirement that the /afs directory should be installed by the filesystem rpm. For my purposes, it would be fine if it's created or installed by the kafs-client rpm or created on demand by the systemd script for starting the mount. Note further that there does need to be a systemd script to effect the mount as this has a dependency on another systemd script that loads the configuration into the kernel. I really don't want to have to tell ordinary users that "you can't use this unless you first go and write some systemd scripting". > \And violating a much more important, namely the File System Hiearchy. > If you can find a good reason to violate that, publish your reasoning. Well, there's 35 years of history, expectation, experience, documentation and scripting for a start that expect the global AFS namespace to be mounted on /afs on a UNIX box (Windows is different). For the in-kernel AFS client to "work out of the box", it must mount the dynamic root on /afs. That is what people who use AFS generally expect. > By the way, I've dealt with /afs style automounting before, and it was > a nightmare to clean up after when it inevitably croaked precisely due > to the root filesystem location of "/afs". "a nightmare to clean up"? "inevitably croaked"? "precisely due to the root filesystem location"? Please elaborate. "umount /afs" or "systemctl stop afs.mount" will unmount the kafs (the in-kernel afs filesystem) dynroot and all its automounts. Note that kafs works differently to, say, OpenAFS. OpenAFS has a single superblock that is the entire AFS namespace and every volume, every vnode you access appears in there. kafs, however, creates a superblock for each volume and uses the d_automount dentry operation to operate AFS mount points.
