more a terminology usage question than anything else, but in a couple of weeks, i'll be teaching the first of a few sessions on RHEL admin and, unsurprisingly, i'll be using centos (as i've done in the past). when i asked the organizer to identify the specific version of RHEL that was being used at the client site, i was told 5.3 so i can easily install 5.3 on the classroom machines, but i'm curious about something and i'll have my contact look into it: if people *initially* install 5.3, is it standard behaviour to still regularly upgrade as new releases come out? obviously, i have to ask my contact to verify what the client has been doing all this time but, in general, what's the normal behaviour for people running centos/rhel? and is there a way to examine an install to see how updated it's been since that original installation? i just don't want to teach off of 5.3, only to find out later that they've been keeping up to date and 5.5 would have been a more appropriate choice. thanks for any tips. rday -- ======================================================================== Robert P.
