-
- Advantages are:
-
- o Good modularity.
-
- o Easy to debug. (You can use an almost normal debugger)
-
- o Easy to enhance.
-
- o Operator can choose servers to run (e.g. choosing what type of file
- system. Or choosing VM strategy)
-
- o Able to configuring the system dinamically. (e.g. adding a new
- device driver without a reboot.)
-
- o Able to have more than one personality (flavor) of OS
- simultaneously. (e.g. Two users are logging on the same machine
- running mach. A user thinks he's using a UNIX System V while the other
- user thinks he's using a Macintosh OS. )
