What I was trying to do, and succeeded with gummiboot and using the
kernel's efi stub, was to bypass Secure Boot but use the rest of the
abilities of UEFI, mainly the use of more than four primary partitions.
UEFI is not needed to use GPT. (E.g. an 11-year-old p4/p4spa+ test-machine
here runs perfectly happily with all (>~4) disks GPT and min 16 (primary)
partitions per disk.)
.
.
For a GPT partition GRUB wants a special partition of it's own (1 Mb).
The first time I started it up I forgot that. I hadn't booted from a
GPT formatted disk before this.
This I did not know. But, with the state of my knowledge today, doesn't
GRUB, used like this, depend on installation in a "Legacy BIOS"
situation? And doesn't "legacy BIOS" mean only four primary partitions?
If there's no partition limitation, then I've been barking up the wrong
tree.
The wikipedia and rodsbooks articles on GPT, might (still - haven't checked
in a while) be worth looking at. (Yes, there are other good refs too.)
In response to both of your comments, I bought a laptop last September
and was brutally exposed to Secure Boot and UEFI hardware. There was a
steep learning curve and Wikipedia, Rodsbooks and Arch Wiki helped get
me to the point I am today. In my upcoming build, I want to go deeper
and get GRUB to help me out.
Until my last build, I'd never used *kit and PAM. Struggled through a
lot and have seen on the list recently discussion of rules for the kits
and PAM. I'd like to have more facility with writing these rules. Right
now, if I have a problem that ends up needed a rule in this area, I need
to appeal to the list for help, and, when the solution is a new or
modified rule, type it verbatim into one of my files.
(( There's much 'Stockholm Syndrome' visible on many tech mailing lists
... ;) .
))
I never thought of myself as being held hostage by {,B}LFS lists. But
now that you mention it, I do remember being restless and unsettled
while pacing in my house waiting for responses from the list. So
maybe..... ; )
Thanks, akh.
