Constantly - naah. But when running Red Hat ('bout 1998-2003 oslt) and
Debian ('bout 2001-2008) something (variating from time to time,
naturally) in the packet kernels has either been made differently than
I'd like or left to be undone at all.
And somehow while using Gentoo compiling also the kernel just makes
sense ;).

Maybe now it is, I remember it used to be an incredible way to install
because you had to do *everything*. I've seen some newer releases that
script some things, though.

Yeah, if you have module support compiled in, you only have to compile
the modules you need, and that does speed things up a bit. If you're
using a monolithic kernel (more common in the "old days") without modular
support, then it was a rebuild.
I used to regularly build my kernels because I wanted features in newer
versions or add-on drivers that were written to a specific kernel release.

Yeah, that could be it. I remember it took *hours* to complete, we
started it and went to dinner, when we came back it still wasn't done.

Well, I've installed it once or twice in my life - I don't know if that
qualifies as "into" it. :-)

Yes, but sometimes one does an "emerge --sync && emerge -uDN world"

I'm joining. Never did that "initiation" exam. ;)

I'm tempted to simply answer with: "Read the rest of that message."
But that probably will just lead to "Why did you have to do it the
first time?"
Answer: I was doing a Stage 1 Gentoo install - which meant compiling
*everything* from scratch. That must, of course, include the kernel.
It's quite conceivable that the default kernel options will miss out a
lot (as it did for, say, DAV support and I believe does for the MPPE
support I need for the PPTP VPN). So you then go and recompile to enable
those.
Then you have my embedded network card. Support for that was needed at
the kernel level. At the time, default kernels did not have support for
it, and you'd have to get it from the manufacturer and compile it as a
kernel module. Probably most popular distributions patched the kernel,
but I was on Gentoo and had to do it myself (which, kind of, is the
point of Gentoo). The kernels include it now by default.
Since I *had* to compile the kernel to install Gentoo(+), I went for
minimalism - I disabled everything I didn't need. Then recompiled
whenever I needed more. As the default setup wouldn't have worked
anyway, and I had to make menuconfig anyway, why not do it right?
Do popular distributions have everything enabled in the kernel by
default? I really doubt it. So none of you has ever needed to install a
package that required some kernel support - only to find that the
distro's kernel didn't enable that feature?
I don't see what the big deal is, and why people keep heavily
emphasizing to others that one shouldn't have to compile the kernel.
It's fairly straightforward, and doesn't break anything for me. In the
old days, you'd have to recompile ALSA and a few other packages
everytime you compiled the kernel, but those days are gone.
(+) Neglecting the technicality that I didn't have to do a Stage 1
install. In my case, though, that was the whole reason I was installing
Gentoo to begin with. And was well rewarded for the effort.

Ugh. You just reminded me of my nightmares with LFS. I didn't learn
much, and mostly copied & pasted the commands. Got it to work. Never
bothered to go forward with BLFS.
LFS *is* good for learning. However, it and BLFS will probably suck
heavily if you want to use it as your primary system and maintain it.
That's what led me to Gentoo.
