+Here lies contributions from the community at large that for one
+reason or another (laziness on my part, and lack of testing, are
+valid reasons!), are not in the main distribution.
+
+If any of these seem particularly stable or useful, let me
+know and I will consider adding them to the main patch.

+ "Thanks for the great vconfig patch/tool. I submit to you a minor
+ change to the RedHat 7.3 /etc/rc.d/init.d/network script that
+ recognizes VLAN interfaces /etc/sysconfig/network-scripts/ifcfg-ethx.y ,
+ and makes appropriate calls to vconfig prior to bringing the
+ interface up. This makes startup more straightforward,
+ and may be of use to your website visitors.
