Don't take things said in public personally. It's common mistake and I will use every opportunity to point it out:-) > But the device > wasn't mounted and I didn't try to access the auto-mount-point. But some other program [such as GUI file system navigator perphaps] could keep doing it for you. I mean you've never mentioned any background infomation such as what distribution and what graphical desktop you run [if any], so we can keep blaiming pretty much anything:-) > As long as I understand the "autofs" daemon, the device is used > when the device is mounted or I try to access the mount-point. Keep in mind that autofs daemon is not the only culprit. There're magicdev, supermount, who knows what else...
