 |
|
Hello all,
My "/boot" directory has somehow become my "/" directory! (or vice versa)
I have been doing quite a lot of tinkering recently so I don't know what caused this problem or when it happened. It became apparant when, having emerged world and got a brand new shiny 2.6.11-gentoo-r6 kernel I decided to compile it. That all went fine. My grub.conf file just points to /boot/vmlinux (with an optional entry for /boot/vmlinux.old in case I need to use the old kernel).So having booted into what I thought was my new kernel I did a "uname -a" and found to my surprise that I was still in the old (r5) kernel.
When I looked into /boot I found that the new vmlinux was there, as was the usual system map and config stuff, but SO WAS mnt etc dev proc usr var AND boot as well as all the other usual / directories. In other words I was not looking at "/boot" but at "/" ! I did a "cd /" and "ls -la" and a "cd /boot" and "ls -la" just to check and indeed the listings were the same!
My old vmlinux files now appear to reside in /boot/boot.
The most significant bit of tinkering I have done recently is to install "ivman" to get my USB stick automounted (see this thread).
What on earth is going on and how do I fix it?
Any suggestions gratefully received.
Many thanks
Mark |

Can you post your fstab file and the output of fdisk -l.

# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:

Any clues?
Thanks for helping...

Errrr, sorry but I'm afraid I don't.
a) The fstab file is a bit of a black art as far as I'm concerned, and
b) It hasn't changed since I set it up a few months ago - it has worked up until now.
Please tell me what it should be.
Thanks for your help... |

You are mounting the same partition to two different places ("/" and "/boot").
You can(should) only mount one partition to one place.
Is /dev/hda8 the root or the boot? |

Doh! Now I get it (I think).
I don't have a seperate /boot partition. /boot is simply a directory on /
I guess that means that I should hust have the / entry - is that right?
Thanks
Mark
Edit : Yup - done that it works. Thanks guys!
I am just a little confused as to why it should suddenly start playing up when it had never been a problem before. Anyhow - all OK now.
Thanks again. |

Because /boot is noauto, so it was only mounted when you installed the new kernel.
The mounting the same partition in two places is analogous to creating a hardlink.
But I thought mount is supposed to complain when you try to mount a partition twice, shows how much I know. |
