We have been operating a cvmfs repository for the Rubin Observatory since a few years now. That repo includes software for macOS and we are starting to experience issues and I would like some guidance from this community.
In recent versions of macOS, the recommended way to share files among users is to store them under
/Users/Shared. Until macOS 10.15 Catalina, the cvmfs client created a symbolic link
/cvmfs --> /Users/Shared/cvmfs.
It seems the the system integrity protection mechanism, included in more recent releases of macOS, prevents modifying the root file system. For instance, in macOS 12 Monterrey that symbolic link cannot even be created because
/ is read-only. There are some turnarounds that imply some gymnastics that are probably not to be recommended for a lambda user.
I understand that the cvmfs client has traditionally required that the repos be located specifically under
/cvmfs. If that is still the case, what is the recommended way for the client to work on macOS 12 Monterrey and later? Is it possible (or foreseeable) for the cvmfs client for macOS to use
/Users/Shared/cvmfs as its top directory? How are people out there handling this issue?
Thanks in avance for your input about this.
