+
+As a point of reference, here's a slightly tweaked analysis of the
+programs on the system I'm reading your mail on. Basically, I ran the
+following script...
+
+ Q> #!/bin/bash
+ Q> function use() {
+ Q>     for Z in $* ; do
+ Q>         strings $Z | grep /proc | sed "s=^=$Z ="
+ Q>     done
+ Q> }
+ Q> use /{,s}bin/* /usr/{,s}bin/* | sort -u | tee proc-usage
+
+...and then went through it removing comments and print format
+strings. Replace /proc with /dev and you'd soon have an equivalent
+list for that - although I can report that such is MUCH larger...
+
+There are three programs therein that refer to /proc/mounts ...
+
+	/bin/mount
+	/bin/umount
+	/usr/bin/eject
+
+...and, as you stated, none that refer to /proc/atm on this system.
+However, as this is a RedHat Linux 5.0 based system, that's not
+necessarily an up to date reference thereto...
+
+Here's the list anyway...
