I am using Fedora 23 and I have autofs set to automount some s3fs FUSE filesystems when directories under /mnt/s3 are accessed. Since I set this up, I always experience an additional delay upon logging in - from looking at journalctl, it looks like something is immediately activating one of those s3fs filesystems as soon as I login - but this fails and times out because the wireless network connection is not yet up.
How can I find out what is causing this unwanted mounting, and/or disable it?
