Are there any special protocols to observe when hot-plugging microSD cards on Raspberry Pi when FreeBSD is up and running? Electrically it's claimed to be ok in this thread by one "jdb": https://forums.raspberrypi.com/viewtopic.php?t=281249 so I'm asking about how the FreeBSD software might react. Obviously filesystems have to be gracefully unmounted, but is that all? Can the kernel be "aware" of an unused device and get confused if it goes away? Thanks for reading, bob prohaska
