You have a point. I'm sure grub or something like it, will be developed as
an alternative to grub2, just as various alternative DM's are. As for me, I
don't really care, just as long as I can boot the damn kernel by typing a
few commands at a grub prompt, I'm happy.

Just from reading Mike's earlier post, it sounds like the answer to
the bulk of those would be:
1) Legacy GRUB didn't do that. Your distro patched it to do that.
2) GRUB2 does it this way. Because legacy grub didn't do that.

It sounds like you're asking for a cookbook. (Which is admittedly
something I wondered about yesterday)

Still, it sounds like most of your menuentries could follow a template
like this:

menuentry '$name' --class gnu-linux --class
gnu --class os {
* * * *insmod $partition_table_module
* * * *insmod $filesystem_modules
* * * *set root='(/dev/which_disk,$partition_table_entry_identifier)'
* * * *search --no-floppy --fs-uuid --set=root
$UUID_OF_ROOT_FILESYSTEM
* * * *linux * $path_to_kernel_from_boot root=/dev/root_fs_disk ro

(Shamelessly adapted from Mike's sample. I removed the video and echo,
as I suspect they're not necessary, and I removed the gzio module,
though I don't know what it's needed for)

I can do this, but it's going to take me a day or two. I have to
refresh myself on GRUB Legacy, first. It has been a (long) while since
I've used it.

Understood, and thanks Mike, I really look forward to reading whatever
you can provide. I realize that I'm gonna have to take this plunge
eventually, and would rather not wait until I'm forced to...

That was my feeling a year or so ago. I saw no point in installing GRUB
legacy on a new system, so I braced myself for all the horrors I'd heard
about GRUB2, only to find it's nice and sensible once you learn what goes
where. I still have GRUB legacy on some systems as they boot fine so no
point in changing, but new installs always get GRUB2.

Neil et al,

Where is the BEST (gentoo) grub2 documentation?
The last link says that the reason grub2 is still
masked, is the lack of documentation

All I've found so far is:
http://www.gnu.org/software/grub/grub-documentation.html
http://wiki.gentoo.org/wiki/GRUB2
http://dev.gentoo.org/~scarabeus/grub-2-guide.xml
http://blogs.gentoo.org/scarabeus/2011/09/17/grub2-4-months-after/

Any other docs/examples for grub2? Something "dumbed_down" for us
older admins, would be keen....

I'm not saying it's the best, but the one I used to switch over is
http://en.gentoo-wiki.com/wiki/Grub2

Default grub vs grub 2

mike, I'd DEFINITELY LOVE to read grub's history, even if it's a short
summary or something.

TOTALLY OFF-TOPIC, but anyone could recommend me a open
source/linux/unix/free software history book? Something that mentioned
the FSF foundation, the GPL creation, the XFree86 -> X.org evolution,
linux [..]. -> 2.4 -> 2.6 evolution, sound stack evolution (OSS, ALSA,
JACK, PA, ESD, Arts, Phonon), multimedia history (ffmpeg, mplayer,
mplayer2, gstreamer, xine, vlc). It could go all the way back to
shell's, like sh, csh, BASH, zsh.
