I had some problems with Acrobat 8 crashing and leaving a process running. In a thread I found suggested to install the lsb package (there are several parts lsb-core lsb-desktop lsb-multimedia etc).

The package description says:
The Linux Standard Base (http://www.linuxbase.org/) is a standard
core system that third-party applications written for Linux can
depend upon.

I am curious as to why this is not in ubuntu by default. (It sounds like an idea Ubuntu would be interested in.) I like to keep a stable system, and I'm not sure what the consequence of installing this will be.

Does anyone have general info about it and also specifically whether it is a good idea to install it?
