I'm a relative Linux newbie and a complete Gentoo newbie. I've amazingly managed to make it to step 17 in the PPC install instructions where it tells you to:

Code:
umount /mnt/gentoo/proc
umount /mnt/gentoo


The first line works fine, but the second one tells me:

Code:
umount: /mnt/gentoo: device is busy


What do I do now?

Thanks in advance.

Make sure you're not 'cd'ed into /mnt/gentoo when you unmount it - try this:

Code:
$ cd /
$ umount /mnt/gentoo


You see, you can't unmount something that's 'in use' and a shell that is 'in' the mounted filesystem (i.e. your current directory) is actually 'using' it.

This happened to me a couple of times. Turned out I was running a program from within the directory. Do a top or ps aux to see if anything has been started there.

Thanks for the quick reply.

I read in the newer installation guide a slightly different order of unmounting the points and it worked. However, now I have a new problem... :(

When I reboot, yaboot freaks out and tells me:

Code:
hd:3,/boot/vmlinux: Unknown or corrupt filesystem


What doesn't make sense though is that when I look at my yaboot.conf file, it looks like everything is correct. I don't know why it's trying to access hd:3. Any ideas on how I can fix this?

Forgot to say I can see my yaboot.conf file by booting from the CD-ROM, and then changing root to /dev/hda4.

Here's the uncommented version of my yaboot.conf:
Code:
boot=/dev/hda2
device=hd:
partition=3
delay=20
timeout=40
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
image=/boot/vmlinux
     label=Gentoo
     sysmap=/boot/System.map
     root=/dev/hda4
     read-only
enablecdboot
enableofboot

OK... I saw where the problem was and changed partition=3 to partition=4.

Now it boots up and gets me to the command line. Uh... being the newbie, how do I get X, Gnome, KDE, etc. up and running?

Sorry for so many newbie questions.

I think there's an additional 'desktop' guide for Gentoo that's separate from the installation manual - have a look around the main site and see if you can find it.

Thanks a lot for your help. I've found what I needed and am well on my way to having a great system running on my Pismo.

So far, between what I've read about Gentoo and the great support and responses in this forum, I think I'll be sticking with Gentoo for a long while.
