My initial question was about passing grub2 parameters through
kickstart so the discussion's a mix of kickstart and grub2.
The kickstart fp.o page referenced above doesn't have any info on
grub2 (unless it's been updated in the last few hours) hence my
question, especially since using 'bootloader ... --append="vga=...
..." ...' in a kickstart configuration file adds "vga=..." to the
grub.cfg "linux" line, which results in a warning at boot that the
"vga=..." setting's deprecated.
The upstream way of setting the resolution is to set
"GRUB_GFXMODE=resolution" in "/etc/default/grub" and run
"grub-mkconfig -o /boot/grub/grub.cfg" ("grub2-mkconfig -o
/boot/grub2/grub.cfg" on Fedora) to re-generate grub.cfg.
Fedora adds a further twist (other than s/grub/grub2/g) because of
grubby. I've yet to create grub.cfg entries with grubby to see how
it's functioning, but if you run "grub2-mkconfig ...", the menu entry
titles are "Fedora Linux ...kernel_version...", whereas when the
kernel's upgraded through yum, the post-install script runs
"/sbin/new-kernel-pkg", which creates "Fedora ...kernel_version..."
menu entry titles through grubby.
OT for this thread but for the record regarding kickstart
documentation: the "part biosboot --fstype=biosboot --size=1"
kickstart entry to create a bios_grub partition on a GPT disk isn't
yet documented on the kickstart fp.o page.
