kernel installation questions

[noone]

hello,

my /boot

is empty  and eselect list kernel is generating an error after installing gentoo-sources:

# emerge gentoo-sources

1. eselect list kernel

!!! Error: Can't load module list
2. eselect kernel set 2 (checked reflecting symlink linux -> linux-4.13.1-gentoo)
4. make xconfig

5. cp /usr/src/linux/.config /usr/src/linux/config
6. make modules_prepare
7. genkernel --kernel-config=/usr/src/linux/config all
8. edit /boot/grub/grub.cfg
9. reboot & pray

 

After installing new kernel I was able to edit /boot/grub/grub.cfg because /boot was populated. However after reboot /boot is empty.

Because Funtoo boots and boot menu reflects my changes then config files are hidden somewhere. However I would like to know where boot config files are located in the case of post boot changes that I would like to add. Unless there is another way of installing kernel and updating config files?

 

thank you

/boot is not automatically mounted by default but was by genkernel,

will have to put mount point in fstab i think.

or do a manual mount when needed.

I just did not pay attention to noauto option in fstab!

 

thank you,

 

p.s.

do you why eselect generates this error?

eselect list kernel

!!! Error: Can't load module list

eselect list kernel

!!! Error: Can't load module list

 

is wrong

# eselect kernel list
then
# eselect kernel set N

eselect  kernel set N (Iwith N = the mumber associated at the kernel that you want to compile.

 

:)

 

For example you can change the "noauto" ....

this is my /etc/fstab ... just for a comparison

The last raw in /etc/fstab is for compile in RAM; but i've 16 GiB .... i don't know your Amount of memory :)

Thank you for helping. Running portage in RAM is great idea (I do the same with CRUX compiling). I just did not know how much RAM I would need for portage. I run Funtoo as virtual guest and I can increase allowed RAM to 16GB.
