Goal of this project was to implement a new automounter, with Sun (as opposed to amd(8)) map syntax, proper kernel support, and LDAP integration. It's very similar to what's available in OS X, Solaris, or Linux. Slides describing the design are here: http://people.freebsd.org/~trasz/autofs.pdf. GitHub repo: https://github.com/trasz/autofs.
The code was committed to 11-CURRENT in August 2014 and shipped in 10.1-RELEASE. Some enhancements, such as mounting removable media, are still being worked on.
This project is sponsored by the FreeBSD Foundation.
