I had no problems with installation in 2011. But I know some that are not used with Pardus have problem here:http://www.linuxbsdos.com/wp-content/uploads/2011/01/Pyali.png
That subject was up in the Swedish Linuxportalen:http://www.linuxportalen.se/blogs/akes/2011/03/03/vad-r-lvm2
When install it in the hardrive it stuck at "create custom layout" automatic and then people click "next" there and just continues.
Then you come to LVM:http://www.linuxbsdos.com/2010/10/25/how-to-configure-lvm-on-pardus-2011/
There you must do many manual choises that a beginner not understand.
When install it suposse go on top automatic to "use all space" then click "next" than it would not be a issue.
If look at the old Pardus 2009 its a automatic option and more easy to understand:http://en.pardus-wiki.org/images/5/5a/Pardus2009ENinstall08.png
Not realy a big issue but I would like that the coming Pardus 2011.1 would have a "default setting" in partitions. So you must active choose another option.
So I can agree with the review in some aspects.
