i hate to open a subject like this but today i was really disapointed because i cant find a recent process limiting for users for linux.
after using unix( mostly linux and *bsd) for three years(i know that it is not much) and continious changing my mind about what is better. i have reach at this conclusions at the moment bsd - type i better than system v type and bsd is slighty better than linux. it's some little diferences that make it better on the other hand , linux has more users and more applications wich is a strong point why someone should use it. but as for security, i really belive that bsd are more secure than linux.
