On 2013-02-02 00:48 (GMT-0500) Felix Miata composed:
# urpmi --no-suggests grub2
which installed only grub2 and os-prober, and took several minutes to
complete (which the known lethargic os-prober is obviously responsible for).
I added a stanza to my master bootloader to load /boot/grub2/i386-pc/core.img
and rebooted, selecting the /boot/grub2/i386-pc/core.img stanza. Results:
Good start:
1-/boot/grub2/i386-pc/core.img in a Grub Legacy stanza succeeds
Not good from then on:
1-Grub2 error message due to not finding some png file
2-25 item Grub 2.00 menu (grub.cfg:
http://fm.no-ip.com/Tmp/Linux/Mdv/grub.cfg.gx27b-cauldron3-1.txt ).
After
selecting a selection from a master bootloader, there's no good reason to see
similar selections as in the previous menu unrelated to the chosen selection.
IOW, when not a master bootloader (i.e. "chainloaded" via core.img, only
Mageia entries attributable to selected filesystem hosting core.img should be
in this menu.
3-Grub2 menu uses same awful spindly-looking font responsible in large part
for my distaste for *buntu
4-default menu selection for Cauldron causes this cmdline:
BOOT_IMAGE=/boot/vmlinuz-prv
root=UUID=bbe8a402-5fb1-4247-b372-5bb6cff4e18c
ro splash
which is nothing like the default Grub Legacy menu stanza's cmdline result:
root=LABEL=22cauldrn splash=verbose noresume video=1152x864 vga=794 3
obviously caused by Grub2 installation disregarding content of pre-existing
menu.lst, which means
5-semi-legible blue on black graphical progress bar instead of normal
complement of startup messages when splash=verbose
6-post ESC, startup messages are inappropriately tiny
7-tty text is too tiny to use (same as startup messages; screen's preferred
mode 1600x1200 used instead of legible mode 1152x864)
8-KDM is on tty2, the location I reserve for certain class of recurring
activities, instead of where expected on tty7
9-preferred initial runlevel as evidenced by menu.lst cmdline options was not
specified
10-tty1 cleared before displaying login prompt (even after customizing
/etc/systemd/sytem/getty.target.wants/[email protected] with
s/TTYVTDisallocate=yes/TTYVTDisallocate=no/; same problem on Rawhide &
Factory; OT)
Such displeasures as 1-9 are the reason why in Grub Legacy vs. Grub2
discussions I point out that Grub2 is still v1.0 software. Just how much of
these observations are due to upstream decisions or yet-to-dos rather than
distro implementation decisions, implementor inexperience or bugs I won't try
to guess.
After editing /etc/default/grub, grub2-mkconfig isn't too bright about
choosing a default kernel/initrd pair:
http://fm.no-ip.com/Tmp/Linux/Mdv/grub.cfg.04
It selected initrd-prv and vmlinuz-prv as default, which are symlinks to the
previously installed kernel.
Upstream still has a warning about use of vga= on cmdline, which is still
valid when KMS is disabled, and when non-Plymouth user wants kernel to use
specified vga= mode instead of 80x25 in the brief init period prior to KMS
initialization.
