Is /boot/grub/grub.cfg the file that actually controls bootup, and is
all 154 lines of verbosity really necessary? For menu entries I see...
=====================================================================
menuentry 'Gentoo GNU/Linux, with Linux production' --class blah blah
blah {
blah blah blah
set root='hd0,gpt1'
linux /vmlinuz-production root=/dev/sda2 ro noexec=on net.ifnames=0 intel_pstate=disable ipv6.disable=1
}
menuentry 'Gentoo GNU/Linux, with Linux production (recovery mode)'
--class blah blah blah {
blah blah blah
set root='hd0,gpt1'
linux /vmlinuz-production root=/dev/sda2 ro single
}
menuentry 'Gentoo GNU/Linux, with Linux experimental' --class blah blah
blah {
blah blah blah
set root='hd0,gpt1'
linux /vmlinuz-experimental root=/dev/sda2 ro noexec=on net.ifnames=0 intel_pstate=disable ipv6.disable=1
}
menuentry 'Gentoo GNU/Linux, with Linux experimental (recovery mode)'
--class blah blah blah {
blah blah blah
set root='hd0,gpt1'
linux /vmlinuz-experimental root=/dev/sda2 ro single
}
=====================================================================
I'd be tempted to do a manual gub.cfg if I had documentation.
