With a Ub9.10 install on a laptop (adding on to a 9.04, with additional partitions,&  having a windows first partition), I can't create a partition in the 10GB free space.  When I did the 9.10 install, it did something strange, hard to explain, something like causing my boot into 9.04 to use the proper kernel, but be using the data space/partition from 9.10. Also, IIRC, I had 2 partitions that gparted showed had the same uuid.

     You were using Gpart were you not? Your complaints mirror my own 
but I did something smart.
I RTFM by clicking on help while I had Gparted displaying my laptop 
partitions. It told me exactly what to do and it worked.

Has that been fixed yet?  What's the state of LVM in current Debian&  Ubuntu?

         You should see Help on Gparted any version.

         I can assure you 9.10 and 10.04 both use the ext4 filesystem 
and Grub2 which is much better than Grub1. These are what I use and yes 
there are some minor problems.

> Well, there are so many questions here, cause there seem to be several deficiencies in various parts of the sw Ubuntu is/has beenusing/used (partitioner in installer, GRUB2, LVM, HAL), I'm looking for any knowledgeable info regarding the current state&  cautions&  future likely status of all this.  Any&  all knowledgeable insight greatly/advice appreciated.
