[OpenAFS] Setting up new cell on RHEL4 - some help needed
Wed, 22 Aug 2007 09:03:00 -0400
for an explanation of the -dynroot option to afsd.
We haven't had a 1.4.x release since I updated the documentation on that.
I know the guide is out of date. I plan to work on that some after I've
updated the man pages.
