Please note that, this is currently considered as an experimental feature so there could be some rough edges. Consult http://wiki.freebsd.org/TMPFS for more information. For now, connect tmpfs to build on i386 and amd64 architectures only. Please let us know if you have success with other platforms. This work was developed by Julio M. Merino Vidal for NetBSD as a SoC project; Rohit Jalan ported it from NetBSD to FreeBSD. Howard Su and Glen Leeder are worked on it to continue this effort. Obtained from: NetBSD via p4 Submitted by: Howard Su (with some minor changes) Approved by: re (kensmith)
