11 Interesting - in that case, I'd have to agree with you and Alan that
12 using make oldconfig sounds like it would be better, and that the guide,
13 official though it may be, is wrong.
14
15 Apologies, Alan, for being a little argumentative - its just that I'm a
16 stickler for always telling people to use 'official' docs as opposed to
17 $random_guide found on the internet, since it should always be 'right'.

31 Heh... agree 100%. In fact, the way it is worded does seem to actually
32 be technically *wrong*, if it does indeed do the same thing as make
33 menuconfig wrt reusing as much of your old config as possible. I would
34 consider the 'shoving the differences in your face' aspect to be much
35 more beneficial too. I probably would have avoided the problem I ran
36 into back when they changed the netfilter options - I can't remember
37 exactly, but I think they changed some of the option names and/or where
38 they were located in the kernel config... all I know is my firewall
39 wouldn't work until I googled the changes and recompiled my kernel.
40
41 So, if no one else (who understands kernel compiling better than me -
42 which would probably be most everyone here) wants to open a bug to fix
43 the documentation/guide, I'll do it, but I think it might be received
44 better if it was made by someone familiar with both methods, but
45 especially make oldconfig...
