This is part 15 in the series of “Beyond the good ol’ LaunchAgents”, where I try to collect various persistence techniques for macOS. For more background check the introduction. I run into this not so exciting persistent method when I was investigating xsanctl for… other… reasons… xsanctl is a “Xsan file system control utility”, which allows us to mount and manage Xsans. The xsanctl binary can be found at /System/Library/Filesystems/acfs.
