I am using grub2 also, but on another distro, with multiple kernels/part= itions. I don't have a lot of firsthand knowledge, because not having a= lot of patience, I usu just drop to the grub cli.

However, IIRC there is a grub2 command called update-grub that scans all= your boot sectors on all your devices. At least that's the way its _sp= osed_ to work - ymmv.

I've just read too much that is system dependant ( version of grub2?) (and to think the purpose of Grub2 was/is standarization?)


So I simple want to be able to add multiple linux kernels
to boot from. Many are experimental hacks, so I keep
quite a few around..... eventually, there will be
a windows7 boot need on lappys and tablets too.

Some reading suggests to simply build the kernels, and
put them in /boot/.... =A0with acceptable namees like:
"kernel-3.10.25-gentoo" and they will automactically
appear in the boot menu? No limit to the number of
images?

Some pages suggest manually editing the grub.cfg file,
but I've also read that this is overwritten by the scipts
and info found in /etc/grub.d. I running Grub 2.00_p5107-r2.

I like to keep multiple version of kernels, complete sources
etc and keep several if not many of the bootable kernels
in /boot/.

Ideas and suggstions on how a grub(legacy) guy should approach
this need, with grub2 are most welcome. Just so you know, I
envision in the next 12 months to have many different arm(64)
systems using grub2 also (linaro has grub2 working on arm and
arm64); so a clean, well thought out strategy of similar
approaches to grub2 on many differnt arch's is what I'm really
after....

Also while we discussing grub 2, it boots blind (no feedback)
and takes too long to boot (estimated 5 minutes) : really slow
so what do I change there? =A0 No systemd on my systems.....


TIA,
James
