11 Rubbish. Let's say tomorrow I plug in a USB sound card, joystick and
12 HSDPA modem. Today I do not have this hardware.
14 Should I rebuild my kernel just to use a hotplug device that I borrowed
15 for a few hours? No, thanks, I'm going to use modrobe.
17 To get my sound card to work, I need a parameter "dell=m42". How should
18 I easily pass this argument without modules? Should I have a webcam
19 driver permanently loaded in kernel space just for the odd case where I
20 decide to use it?
22 1995 called, they say they want their hardware back.

31 If a crap programmer writes a module, it will be crap and do $BAD_STUFF.
32 How does this change if the crap programmer is forced to not write
33 modules? Does he suddenly get enlightened and know what K&R have been
34 telling him for years?
37 THIS.

55 That type of usage is not my area of expertise, but I can tell that it's
56 a niche market. If monolithicality is the correct design paradigm
57 there, then the designer has the option of building a monolithic
58 kernel. If you can coerce it to work on Intel cpus, well that's fine
59 and dandy and attests to the power and adaptibility of Linux.
61 But how does this support your assertion that modules are a bad idea?
62 You have the choice to do it a better way in those circumstances.
63 Meanwhile, the vast majority of server nd desktop deployments out there
64 that truly do need kernel modules (including Gentoo) cna and should
65 continue to use them.
