No. As long as SUSE supports the file system on /home you're using in Gentoo it will work fine, and that's very likely. When you're booted into SUSE, run cat /proc/filesystems to see what it supports. If your Gentoo /home file system is not there, you may need to load the module, eg. on this system; # grep ext /proc/filesystems ext2 ext4 # modprobe ext3 # grep ext /proc/filesystems ext2 ext4 ext3
