Seems I can't reply to a top board level post here: http://kubuntuforums.net/forums/inde...opic=3118477.0, so I reposted the the whole post here:
The answers seem correct at a quick glance (it might be easier to dig deeper if you explained what seems out-of-place to you, aside for the few "typos" in the answers), a few quick notes:
1. df (see 'man df') will show the usage status of mounted partitions (not the only one, but one that is commonly installed by default...in *buntus it's part of the 'coreutils' package). Similarly, 'man which', 'man hexdump' and 'man xauth' should give you details on the commands.
2. killall -sUSR1 apache2
3. /var is often set up as a separate partition on large multiuser/server installations so users (or user processes) wouldn't be able to fill the root partition (either intentionally or unintentionally) because var needs to be user writable because user processes commonly store mostly temporary changing data in /var. Of course users home directories (/home) should also be on a separate partition(s) in such environments.
A friend of mine is studying for a certification test and this is one of her practice exams she gave me. My question is can anyone off the top of their head give me a quick explantion on why these are the answers or even if they are correct? I don't want to trouble anyone with this as I really shouldn't be posting this here, I just hope this may be fun for some poeple. To me some of this just looks wrong but thats why I will be buying a study book before I think about taking any test, (Which I will have to finsh the MCTS Server 2008 Active Directory I'm working on first
