Indeed -- that's just what I had been doing, but simply hadn't looked in the "right" places -- e.g. /proc/tty/ et al, as I mentioned in the original post. The hint about /proc/cmdline/ took me right where I needed to go. For this, and other potentially useful information. :-) > There's useful stuff in /proc >(commandline for the kernel, maybe some stuff for processes), there's >the environment - the console stuff may be there too. Some, but nothing else I've seen so far has proved as useful as /proc/cmdline/ for this particular "what's the console?" purpose. One of the first things I did when starting Kickstart work was run a handful of simple things in %post to figure out "what's available"; e.g. the shell environment, as you mentioned, and basic commands like 'df' and 'ps' and 'env' and etc., just to look for interesting things to make use of during the install. >You _can_ find your server if you're doing ftp/http (nfs too I think), >and potentially get more info there, perhaps a profile or script that >makes futher customisations. Exactly -- the basic routine I've seen here and elsewhere, and have happily taken advantage of: - run a small script (or just shell commands) in %pre - use that to build a customized %include - use %include in general or %post is a very useful notion for many types of cat-skinning. :) Cheers, sr. -- || Steve Rikli ||| || || Systems Administrator ||| Good, fast, cheap: choose any two. || || ||| || || sr@xxxxxxxxxxxx ||| ||
