Howdy,
Just compiled the new kernel [3.10.7], was about to edit my
/boot/grub/grub.conf, and found it missing:
box0 boot # pwd
/boot
box0 boot # ls -a
. .. kernel-3.10.7-gentoo kernel-3.8.13-gentoo
What did I miss?
Do you have /boot in a separated partition? Did you mounted it?
Nothing should touch /boot, AFAIK.
Regards.
I do have '/boot' on a separate partition. If I understand it correctly,
'/boot' gets mounted every time at system start-up, based on
'/etc/fstab', does it not?
By the contents of your fstab, it should...
box0 boot # cat /etc/fstab
<snip>
/dev/sda1 /boot ext2 default,noatime 0 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext4 noatime 0 1
/dev/sda5 /home ext4 noatime 0 2
/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
box0 boot # mount|grep /dev/sda
/dev/sda3 on / type ext4 (rw,noatime,data=ordered)
/dev/sda5 on /home type ext4 (rw,noatime)
,,,however mount says up there that it's not mounted.
box0 boot # fdisk -l /dev/sda

For some reason your /boot partition didn't get mounted. See the boot
logs, and try to mounting by hand. Perhaps the fsck failed or it needs
manual intervention.
Regards.
Based on the 'dmesg' output below, EXT2-fs attempted to mount the '/'
partition instead of the '/boot' one.
box0 ~ # dmesg|grep 'EXT.*fs'
[ 2.444214] EXT2-fs (sda3): error: couldn't mount because of
unsupported optional features (240)
[ 2.444736] EXT4-fs (sda3): couldn't mount as ext3 due to feature
incompatibilities
[ 2.481412] EXT4-fs (sda3): mounted filesystem with ordered data
mode. Opts: (null)
[ 9.448819] EXT4-fs (sda3): re-mounted. Opts: (null)
[ 9.731383] EXT4-fs (sda5): mounted filesystem with ordered data
mode. Opts: (null)
Would that suggest a corrupted /boot/grub/grub.conf file?
Not necessarily. Can you manually mount /boot and see the contents of
/boot/grub/grub.conf.
How did the system boot then?
If grub can see the boot partition (and is correctly configured and
installed on the MBR), it can mount the root system without problems
regardless of fstab. Do you use an initramfs?
Regards.
'mount /boot' fails:
box0 ~ # mount /boot
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
No, I do not use 'initfamfs'.
What do you suggest doing?
Mounting it by hand:
mount -t ext2 /dev/sda1 /boot
Regards.
That did the trick. Thanks very much.
Here's my /boot/grub/grub.conf:
box0 linux # cat /boot/grub/grub.conf
# This is a sample grub.conf for use with Genkernel, per the Gentoo handbook
#
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10#doc_chap2
# If you are not using Genkernel and you need help creating this file, you
# should consult the handbook. Alternatively, consult the
grub.conf.sample that
# is included with the Grub documentation.

Is there anything that suggests as to why the /boot partition failed to
mount at system start-up?
No, I don't see anything that. However, since you cannot "mount
/boot", but doing it manually works, that means something is wrong
with your fstab. Can I see it again? There is no /boot/etc/fstab,
right? What does /boot/grub/device.map say?
Regards.
Getting late. I'll have to chase it up tomorrow. Sorry.
Thanks heaps for your help.
I'll keep yourself and the list posted on the progress made.
