Hello everyone,

This weekend I installed Gentoo in Virtualbox, in EFI mode.
I successfully completed the installation, but I was wondering why /boot is empty.
I can start the machine correctly, but my kernel, initramfs & system map are not showing when doing an ls /boot.

Yesterday, I have upgraded grub to 2.0.2-r1, then I re-installed my grubmk-cfg, according to the manual and recompiled my kernel, because grub seemed to have erased my directory.

Where can I find my kernel, grub, etc.. under normal usage?? :s
Did I do something wrong, and how can I correct this??

When I boot the VM up with Sysrescuecd, I see the following, when mounting /dev/sda2 on /mnt/gentoo/boot (I have to create this first, livecd env.),
I see the EFI, grub, and Kernel, initramfs & SystemMap??

Do I need to pull in efibootmanager (?) or do I have re-start again?

Thank you,
Kind regards,
V

This is my /etc/fstab,

Code:

# <fs>         <mountpoint>   <type>      <opts>      <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# NOTE: Even though we list ext4 as the type here, it will work with ext2/ext3
#       filesystems.  This just tells the kernel to use the ext4 driver.
#
# NOTE: You can use full paths to devices like /dev/sda3, but it is often
#       more reliable to use filesystem labels or UUIDs. See your filesystem
#       documentation for details on setting a label. To obtain the UUID, use
#       the blkid(8) command.

/dev/sda2      /boot      vfat      noauto,noatime   1 2
/dev/sda4      /      ext4      noatime      0 1
/dev/sda3      none      swap      sw      0 0


Here-under, you can find of the parted setup of my disk

Code:

Number Begin End    Size   Filesystem Name Flags
1          1 MiB  3 MiB 2 MiB                 grub   bios_grub
2          3 MiB  131MiB 128 MiB fat32  boot   boot,esp
3          <-> 2 GiB linux-swap(v1)      swap
4          <-> 30 GiB ext4                   rootfs


Ps. I have added grub under protected packages with a emerge --noreplace :s, how I can undo this?

Thnx

Sounds like you ran ls /boot with /dev/sda2 not being mounted at /boot. When using a separate boot partition (/dev/sda2) the /boot directory(mount point) should be empty. run
Code:
mount /boot # fstab and mtab tell mount to use /dev/sda2
ls /boot
to see the missing
If you forget to mount the boot partition as often as I used to, you can remove noauto from your /etc/fstab

DONAHUE,

Removing "noauto" did the trick, I see the contents of boot now after restart,

Thank you,
Kind regards,
