well, this is more of a doubt than a problem. in previous versions of openSUSE [11.0 and 11.1]I could use the following characters ,] to give names to my GRUB settings, eg:
openSUSE 11.1
openSUSE 11.1 [Failsafe]
but now, I installed version 11.2 and when I try to use [or]it tells me that characters are illegible, and I have to use parentheses. 
is something that only happens to me, or is due to a general change in the GRUB?
Thank you!
