The latest Sabayon installs wonderfully, easiest I've seen yet for nvidia drivers and beryl working ootb. And I love the theme and look of Sabayon, to me it's great.

But it's after install where PClinuxOS beats Sabayon - and the pclos install is only slightly less easy. The pclinuxos control center beats anything any other distro has for settings management and it also uses synaptec, which is great. As of yet, Sabayon can't do a system wide update, emerge world, safely. Things will break. Nothing beats synaptec.

But I digress, I found this thread after searching for 'ipv6.' I just installed the 3.0 beta - which overwrote my pclinuxos grub without asking or warning :x , and now when I try to boot into it comes up with:

"Checking root file system
fsck 1,40-WIP (14-Nov-2006)
/dev/sda9: clean, 1007961/1713600 files, 625511/3421837 blocks
modprobe: WARNING, Not loading blacklisted module ipv6

Checking file systems
fsck 1,40-WIP (14-Nov-2006)
modprobe: WARNING, Not loading blacklisted module ipv6

dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/hdb10, 21560 files, 1267340/1726643 clusters
modprobe: WARNING, Not loading blacklisted module ipv6"

And then it stops. Any thoughts or ideas on this?

Mint is installed on a partition on a sata drive. The swap and the fat32 storage partition it doesn't like are on an ide drive. The system is an amd 5600 X2 cpu on a asus mobo with 2g of ram. The video card is an nvidia 7900GS.

Linux Mint is funded by ads and donations.

Please start a new thread when you have a new problem. This increases your chances to get an answer and keeps the forum neater, people can see when some new problem arrives.
Now, Mint and Ubuntu does not owerwrite grub. It adds itself to an existing grub and makes the list in menu.lst longer. pclinuxos on the other hand ruthlessly overwrites an existing grub (personal experience). It only cares about Windows - I have started a thread about this recently (in "Installation and boot")
The only thing I can come up with is that there was some abnormality with your existing grub (other than being a pclinuxos one :))
//edit//
On a second thought - if you've come so far - the problem is not with grub - you should have seen the list of different linuxes to choose from. Grub is most likely OK, but something with your filesystem is not. You could try to disconnect the offending IDE drive and see what happens. OK - you won't have swap, but it should boot anyhow, but with a performance hit. If it boots ok, you have to take care of your IDE drive. //
To your questions:
Ipv6 is blocked because the module "hampers" ipv4 and as ipv6 is hardly used you might as well block it. This is by default.
You could use the live cd. When you open gparted all partitions opens up.
I don't think they are mounted before - but I haven't checked - do that.
You should be able to edit menu.lst in the Linux you installed last to correct things, and that was Cassandra I presume?
Anyway below is a suggestion for a grub with Cassandra an PClinuxOS. You have of course to change the disks to what you have
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# Pretty colours
#color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

# examples

# title Windows 95/98/NT/2000
# root (hd0,0)
# makeactive
# chainloader +1
#
# title Linux
# root (hd0,1)
# kernel /vmlinuz root=/dev/hda2 ro
#

#
# Put static boot stanzas before and/or after AUTOMAGIC KERNEL LIST

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=fe7f6b13-b368-42e1-8953-e5c7ed8ce265 ro

## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,12)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## ## End Default Options ##
