[gentoo-user] About "make install all" when kernel building

[Harry Putnam]

I have a newish install I've been running for a while.

Today I added a setting to the kernel and rebuilt.

The final move I made on the kernel move was

  "make install all"

No looking at the /boot/grub/grub.conf all I find is the example file
that comes with install.

If there was old version before calling "make install all" , it has
been removed I guess.

I've created a version from a very old one I had in some very old
backup and wondering if all the options on the kernel line are still
valid. (I do have the VESA ahd vesafb (frame buffer) and mtrr stuff
checked in the kernel config). And "root" is at /dev/hda4

,----
| default 0
| timeout 10
| splashimage=(hd0,0)/boot/grub/splash.xpm.gz
| 
| title Gentoo Linux 4.1.6
| root (hd0,0) 
| kernel /boot/vmlinuz-4.1.6-gentoo root=/dev/hda4 vga=0x31A video=vesafb:mtrr,ywrap
`----

I'm pretty confident of everything but the kernel line.

Before I reboot, find it fails to boot,  and have lots of huffing and
puffing starting up with grub commands or having to go back to an
install .ISO to get insdide, I hoped someone here could tell me if my
grub.conf is likely to work

That config looks fine. However, you only have one kernel stanza. To be
really safe, copy the old one to a second entry and clearly label it as
the old one. Then you can select it if the new one does fail to boot.

It's easier that way than trying to edit it in grub's editor

Many thanks... I remember there being those old kernel lines now that
you mention it.... I probably would have proceeded though without your
comment.
