+$NetBSD: MESSAGE,v 1.1 2008/07/31 03:58:05 bjs Exp $
+
+NOTE: Unfortunately, JACK wants to use a linux /proc filesystem to
+perform shared memory housekeeping tasks. Therefore, if your platform
+supports a "Linux-compliant" proc filesystem, we recommend mounting one
+prior to using jack. On NetBSD, this can be accomplished with the
+following command:
+
+ mount_procfs -orw,linux /proc <mount point>
+
+Conventionally, the mount point is /proc. If you wish to use a different
+pathname for this filesystem, you may define the JACKD_PROCFS_PATH
+variable in your build environment or mk.conf as shown below.
+
+ JACKD_PROCFS_PATH= /emul/linux/proc
+
+ATTENTION: NetBSD-current users who wish to run jackd with real-time
+ scheduling will likely find that the loader fails to mmap
+ the driver module(s) when using -R. Until this issue is re-
+ solved, one may work around this problem by using the -m
+ (--no-mlock) option.
