That did the trick. Thanks very much. |

Here's my /boot/grub/grub.conf: |
| 108 |
box0 linux # cat /boot/grub/grub.conf |
| 109 |
# This is a sample grub.conf for use with Genkernel, per the Gentoo handbook |
| 110 |
# |
| 111 |
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10#doc_chap2 |
| 112 |
# If you are not using Genkernel and you need help creating this file, you |
| 113 |
# should consult the handbook. Alternatively, consult the |
| 114 |
grub.conf.sample that |
| 115 |
# is included with the Grub documentation. |

Is there anything that suggests as to why the /boot partition failed to |
| 132 |
mount at system start-up? |
| 133 |
|
| 134 |
Thanks. |
