If I followed the kernel instructions page correctly, its E8400 Core2Duo |
| 2 |
wasn't in need of an initrd, and so did not get one. Main deviation from |
| 3 |
suggestions/defaults was enabling HPFS filesystems. Result was 6001056 byte |
| 4 |
4.0.5. openSUSE Tumbleweed 4.0.5 kernel is virtually identical at 6004656, |
| 5 |
but there is also its 8712096 initrd. |
| 6 |
|
| 7 |
I reached the bottom of |
| 8 |
https://wiki.gentoo.org/wiki/Handbook:X86/Installation/Bootloader and |
| 9 |
restarted host before clicking on link to next step. Before emerging |
| 10 |
recommendations in the Tools instructions page I took a timeout to emerge mc. |
| 11 |
The process involved 22 packages, more than I had any idea mc depended on, |
| 12 |
but I guess that's at least partly because the installation to that point was |
| 13 |
so very skeletal. |
| 14 |
|
| 15 |
I got ahead of things I suppose on the bootloader instructions, which include |
| 16 |
no example for Grub 0.97. I did emerge -s grub to identify the package name, |
| 17 |
then did 'emerge --ask sys-boot/grub-static' without first looking for any |
| 18 |
instructions, after which I somehow found https://wiki.gentoo.org/wiki/GRUB |
| 19 |
and its instruction saying 'sys-boot/grub:0'. Having already emerged |
| 20 |
sys-boot/grub-static without the :0 appendage, I punted instead of looking up |
| 21 |
meaning of :0, running 'emerge --ask sys-boot/grub-static:0'. That produced 4 |
| 22 |
beeps prior to emerge exit, which the previous emerge did not do. Next I set |
| 23 |
Grub up according to its man page: grub> find /boot/grub/stage1; grub> root |
| 24 |
(hd0,21); grub> setup (hd0,21), then adjusted grub.conf. |
| 25 |
|
| 26 |
First boot try I used Gentoo's Grub 0.97 (grub.conf) chainloaded from |
| 27 |
openSUSE's Grub 0.97-194 (menu.lst). Kernel quickly panic'd. I recognized |
| 28 |
nothing on the screen to indicate why, though I had seen such things before, |
| 29 |
among them, not syncing: VFS: Unable to mount root fs on unknown block(0,0). |
| 30 |
/ filesystem is mkfs.ext4 created while running openSUSE kernel 3.12.44. |
| 31 |
|
| 32 |
Second try I used menu.lst. Fastest boot I've ever experienced! |
| 33 |
|
| 34 |
I then tweaked on grub.conf, but #3 try using it also panic'd (~@1.37), also |
| 35 |
producing no help I recognized. |
| 36 |
|
| 37 |
So now after some experimenting with cmdline arguments I'm on ~#10, headed |
| 38 |
into https://wiki.gentoo.org/wiki/Handbook:X86/Installation/Finalizing , |
| 39 |
wondering why a Gentoo sample/prototype-based Grub stanza produces panic. |
| 40 |
|
| 41 |
Panicing grub.conf cmdline arguments: |
| 42 |
root=/dev/ram0 real_root=/dev/sda22 ipv6.disable=1 net.ifnames=0 splash=0 |
| 43 |
video=1024x768@60 3 |
| 44 |
|
| 45 |
Working grub.conf cmdline arguments: |
| 46 |
root=/dev/sda22 ipv6.disable=1 net.ifnames=0 splash=0 video=1024x768@60 3 |
| 47 |
|
| 48 |
Why is root=/dev/ram0 real_root= in the sample/prototype? |
| 49 |
|
| 50 |
4.0.5's /boot/config* FWIW: |
