==== Install Base ====

  - Install Kubuntu Edgy (6.10) Alternate Install: F6-F6-Expert Mode
  - Install Ubuntu Hardy (8.04) Alternate Install: F6-F6-Expert Mode
  - Install Raid1 with MD package activated
  - DO NOT install LVM during initial setup
  - Boot into KDE from HD
  * __Note__: if MD oder LVM already activated before and need clean: 2nd shell (Alt-F2) > mdadm - -manage - -stop md0 > mdadm - -manage - -remove md0 before writing to disk in partitioner

==== Check wether all volumes get mounted during system boot ====

to check wether root and swap are mounted, enter:
  mount
  free -m -t

to check mismatching uuid's, enter:
  ls -la /dev/disk/by-uuid
  cat /etc/fstab

to fix, do:
  vim /etc/fstab
replace the uuid's found in fstab with the ones found in /dev/disk. Make sure you copy the correct uuid (md0, md1) to the respective entry in fstab.
