Thank you, Jorge.  I will do so, going forward.

I was kinda freaked out.  I depend on my desktop system for so many
things in a day, and it's _way_ behind in updates, I know.  I got pushed
into a kernel update by a simple software mod, which required a perl
update, which required that I run perl-cleaner, which has issues of its
own, and somewhere along the way I ran into a dependency on a newer
version of udev, which depended on a newer kernel, which I'd tried to
install before with the same or similar problems.  I couldn't make
things work and had to resort to a rescue disk to back out.  I felt
cornered, and I guess my plea for help showed it.

I actually have enough knowledge and experience with Linux that I can
probably solve this problem myself if I approach it methodically with a
clear head.

I can eat crow with the best of 'em, Jorge.

Ah!  Thanks for the heads-up on this.  This switch is _not_ on in my
newer kernel, and doesn't exist in my older kernel.  CONFIG_SYSFS,
however, _is_ on as I assume it should be for /sys on which udev
depends.

I don't know why udev hasn't been completely integrated into kernel
development.  It's become so much a part of modern Linux and is so
interdependent with the kernel.  Yes, it's in user space, but so are
other kernel hooks.

Question:  There are switch and value dependencies in the kernel that
are Gentoo specific, or specific to system configurations favored by
Gentoo (similar to what you mentioned above).  If I emerge a Gentoo
kernel, are the default configuration options for that kernel set by
Gentoo devs so as to build a kernel which will avoid these kinds of
"gotchas"?   In other words, if I build a gentoo kernel out of the box,
as opposed to a vanilla kernel from kernel.org, do I gain an advantage
with regard to possibly problematic configuration options on a fairly
standard Gentoo system?  I hope this makes sense.

Jorge, thank you SO MUCH, for this, (and for being an adult in the
sandbox.  I wasn't at the top of my game today :-)
