Linux Desktop Deployment Postmortems?

duffbeer703 asks: "My employer runs alot of desktop and laptop computers -- something in the neighborhood of 40,000 PCs. Currently they are all Windows 2000 & XP managed by Active Directory and other big, complicated enterprise management tools, all of which can support Linux in one form or another. I'm looking for ways of making Linux (and maybe Unix or even Apple desktops) an option as we replace or add PCs. The problem is, most of the resources that you find online about deploying Linux focuses on server environment, and the articles that I do find about desktop Linux focus on standalone developer workstations, the IBM conversion to Linux (which doesn't seem to have happened) or things like LTSP, that won't integrate well with our infrastructure. Is anyone out there successfully using Linux for regular users? How did it go, and how did your IT and user communities adapt to the new kid on the block?"

Ghost et al.

I was able, at some point a few years back, to produce a Ghost image with Red Hat, OpenOffice, and a login model that used my office's Windows infrastructure to authenticate users automatically. It worked very well. I used it on several test PCs and was able to boot them up, ghost them, and have them come up connected and ready to use.

It was fairly straightforward to set things up with simple additions to /etc/skel. The only real kneebiter was the fact that the vast majority of the office required Outlook, and for some reason (I don't recall what) Evolution wouldn't quite cut it. I seem to recall problems with lookups in the Active Directory using Evolution, but for all I know that's been fixed by now.

I ran this thing on my PC for months before my employer even noticed. I used VMware for my Windows needs (as I was a network administrator, I needed to run some troubleshooting in Windows for user support) and Samba for all of my day-to-day shares and printing. In the end, the only reason anyone knew what I was running was that I was sick one day, and someone tried to sit at my desk, with very small amounts of success.

Now if only I'd kept a copy when I was let go!

Disaster

I used to work at a private high school in the Northeast. You can probably figure out what one by looking at my user name. Anyhow, we (read: I) tried a rollout of Linux on our file servers and routers. Here's what happened:

The Linux file server worked beautifully. We had a simple NT4 domain, setting up Samba with proper permissions was easy. It was easy to administer, very reliable, and fast.

The Linux router(s) worked well, too. I had a nice collection of scripts run with cron that would turn off internet access to the dorms at a specified time, and then turn it back on in the morning (remember: this was a high school).

I was even in the process of developing a grading system with the LAMP stack, since at the time, teachers did their grading manually, and often complained about it.

Everything was running beautifully for months, until politics entered the game. Some higher-ups bought software without consulting the IT department (me and one other guy) that of course only ran on Windows. They also decided that we were going to go with FileMaker for a grade database, that was maintained by some high-price consultant. In the end, they wanted everything to be Windows for some reason or another (misinformed about how Open Source works, you know, the whole deal). My wonderful little Linux environment disappeared, and eventually, so did I.

Moral of the story: technical challenges aside, your project can always be torpedoed by someone who is self-important and more powerful than you.
