Subject: RevRdist and why I like it
Date: Tue, 1 Dec 92 22:47:15 EST
(Bill, if this is too long, please feel free to put it into the archive, but
it probably doesn't rate as a big deal text thing)
Hi guys,
There have been some wuestions asked re the programs: RevRDist vs. FolderBolt
vs. AtEase lately.
In particular:
I need to evaluate these three programs in preparation for protecting some
40 Mac hard drives. Over the semester break I and another co-worker will be
installing some 40 Mac hard drives in preparation for upgrading to System
7.x.x.
Since I don't want to have to closely watch every single drive for contraband
software which students in our open labs WILL install on the disks. I have
heard good things about the program RevRDist which was written at Purdue
Univ.
I have little experience with At Ease or Folderbolt, (I was put off by the
prices of folderbolt, and the bad things I had heard about it's awkward
reaction with some drivers, and At Ease wasn't released when I was doing the
investigation.
I have had lots of experience with RevRdist and would heartily recommend it if
your needs are similar to mine.
First: what does it do? It essentially makes a machine capable of reading a
"recipe" of what it should have on its hard disc, including system
configuration from a file server.
Here's why I need it:
I teach in a K-12 school that does a lot of industry training. Hence, we can
have kids of 4 years old playing Kids Pix at four o'clock and Advanced
Photoshop or Filemaker courses running at 5pm. Imagine the hassles that this
can provide!
I used to have all sorts of interesting things like fonts changed, software
missing, etc etc sprung on me just before I was to begin teaching. The best was
some kind individual who donated a huge sound file and set the system beep to
this sound. The best because it wasn't obvious.
I began teaching, one of my students caused a system beep and we were
entertained by the first 2 minutes of Also Sprach Zarathustra!
Because of the range of uses, we also need to turn modify the software
configuration fast. It took me about 30 minutes last week to change the
software and system complement of 25 machines. Most of this time was taken up
in deciding on the exact complement!
Here's how it works:
A better explanation will be found in the ReadMe and manager's guides available
from Purdue, but basically, I write a text file in a wp that lists the folders
and or files that I want affected, and how I want them affected. eg I may want
to replace any modified applications, chuck out all "donated" inits to the
system and move documents from their inevitable location on the applications
folder to a root level folder called "Lost & Found" (if this sounds like unix
then it's because that's where it came from)
I fill in the blanks of a prefs file that holds info on when to check the local
HDD, where to find the text file and where to find the hard discs contents
should anything need to be updated or replaced.
I create a folder on the server called "client contents" (it can be called
anything - this just sounds good) that contains all the stuff I want on the
HHDs.
I create an emergency disc that will log on to the server automatically and
teach some people how to delete the HDD system, select the network control
panel and change if any cretin has changed it from Ethertalk to Locatalk, and
copy a new system folder from the server and restart.
This has taken me about 2 hours (if that).
I now have a system that will look after itself for ever and a day.
I can confidently tell my year 9 class that if the scratch disc is too full for
their Photoshop artwork, then delete a swag of software to make space, just
make sure that you restart before you leave. 10-15 minutes later (depending on
how much was removed) the machine is ready with a fixed, consistent appearance
and software complement.
ps I also use things called PRAMset to change the really nice plaid desktops
that I get back to basic grey, a set time init that syncs the client machine's
clock with the server and a lock volname init that stops kids from changing the
Hard drive's name.
I can't recommend RevRdist enough - the purdue mob have done a great job and it
has saved me heaps of time and I really like the cost.
BTW, if any of you Purdue people are going to be in San Francisco for MacWorld,
leave a message for me at the Sheraton Fisherman's Wharf - I'd love to buy you
a beer or three.
Cheers
Martin
