This will give you the general overview: http://people.redhat.com/~jmoyer/autofs-linux_kongress-2005.pdf A slightly newer one is available in the OLS 2006 proceedings, here: http://www.linuxsymposium.org/2006/linuxsymposium_procv2.pdf > What I would like to understand, above all, is the detailed interaction > scheme between automount and the kernel.

The autofs file system traps lookup requests. It then passes the requests on to the userspace daemon to perform the actual lookup of the key in the automount map and to then perform the mount. This is done in a userspace daemon because it is too complex to be handled in the kernel.
