We migrated (delete and create) our shared data partition from FAT32 to EXT3.
The shared data partition on the Ferrari is a read-write partition for Windows XP and SUSE Linux 10.
Linux
Created a new EXT3 partition and moved the /home directories to the new partition.
set the mount point in /etc/fstab to /home
Windows
We use ext2fsd to mount the partition on windows as drive d: (mount 0 4 d:)
not tried this one, but looks good (http://www.fs-driver.org/index.html)
Both OSses share the data partition for OOO, ifolder, firefox, gaim and other data and config settings.
To solve the .dmrc issue make sure your home directory has 755 permissions.
O and Wouter
once you have the new filesystem
do 'init 3' to exit your GUI (gnome or kde) GUI settings are also stored in your home dir
Create a home directory on the new file system (mkdir /home)
Set permissions (chmod 755 /home)
move your data (cp /oldhome /home)
Add the new file system to your fstab file (pico /etc/fstab)
Here is my fstab
