16 Thanks... but you hit on something there that can throw you.
17 scsi stuff.
18
19 I've never used a scsi hard drive in my life but not that long ago
20 linux users needed scsi support for many of the cdrom drives. I doubt
21 that is still the case but it might be. But my point is that even
22 when you think you know something isn't needed it might be in some
23 context you haven't thought of.

25 People in this thread speak of 2 and 3 boots and editing in between in
26 the same message where `5 minutes' is mentioned. That doesn't wash.
27 You're way past that time frame. But still not in the guiness book
28 realm I guess... hehe.

35 Just to know more on this... Is there really any reason to worry about
36 kernel size... I mean in most cases with a standard desktop install?
37
38 I noticed a massive difference in drivers and modules installed
39 between a machine running kde and X and a hand roled kernel I
40 configured on nox system with just basic install. In fact that is
41 what led to my post here. But the actual kernel wasn't all that
42 different in size.

49 Do you mean on this thread? If so I must have some trouble with my
50 newsreader threading or something... I don't see it here.

58 ... And thanks for the basic advice and comments.
