AVDF missing boot partition

While working on the problem with missing RAM on the AVDF test system (see ) I realized, that the linux boot partition is not available by default.

[root@melete2 log]# ls -al /boot
total 16
drwxr-xr-x  2 root root 4096 Jan 11  2013 .
drwxr-xr-x 24 root root 4096 Jul 11 20:19 ..

[root@melete2 log]# df -kh /boot
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_root-lv_root
                      6.6G  2.2G  4.1G  35% /

Initially I was a bit confused since it contains stuff like grub configuration, inited.img, kernel etc. All stuff that are needed for system boot. Ok, I have not thought about that for the bootloader, the file system does not have to be mounted. From the security point of view it’s even better to not have it mounted. If not mounted nobody can accidentally change something. 😉 Oracle has defined noauto for the boot partition. Therefore the device is not mounted automatically during system boot.

[root@melete2 log]# cat /etc/fstab|grep boot
LABEL=/boot                    /boot                    ext3   noatime,noauto,nodev,nosuid                  1 2

If you need to change the grub configuration just mount the boot partition manually.

[root@melete2 log]# mount /boot

[root@melete2 log]# vi /boot/grub/grub.conf

[root@melete2 ~]# umount /boot
