"Won't Webmin reduce a lot of Linux sys admins to the level or point and click Windows admins again"
I think using the word 'reduce' there is a bit leading. I don't need a expertise in mining and metallurgy to use a spanner, provided it's a quality spanner that I can rely on and I know where to get another one.
I'm a linux administrator of 7 years experience. I have about 30 servers under my care and I configure everything via the command line because I'm not prepared to erode security, stability, portability or available resources for the sake of being able to work a little faster using graphical utilities. In my experience, the most consistent and reliable configuration utility is vi on a shell.
Bacula is testing this philosophy. It's so disproportionately complicated to configure it to do something straightforward and consistent that it is almost not worth the effort. The manual is nonlinear and inaccessible, and I have found myself learning to use bacula through the continuous wrenching of experience, instead of just reading up on it. Judging by the number of emails to the bacula users list I am not the only one. It's the one service I administer that will repeatedly behave in an unexpected manner.
If a webmin module means I can start to depend on bacula then I may have to move away from the command line on this one.
