Thanks a lot for your reply, kashani ! :)

 Hrrrmmm...I am not a native English speaker...I am not whether I
 understood your first sentence correctly...

 Did you mean: On a home system it is no advantage to use LVM or did
 you mean: On a home system there is no disadvantage when using LVM
 (or did you mean something totally different ???)

 I will use LVM "strictly home"...

 And yes: "You can tell a programmer many things, but you can't tell
 him where to put his files." TRUE! I am a programmer (but the system 
 with or without LVM I have in mind is not for my profession but for
 my hobby...) and know that your are right :) X-}

 What's about fragmentation of data, when using LVM ?

 Keep hacking!
