Hello, I have dedicated server on CentOS Linux 6.1 with  
webmin/virtualmin and it tell me:

Package updates 	145 updates to system packages are available. Use the  
Virtualmin Package Updates module to install them selectively.

4 updates to Virtualmin packages are available. Use the Virtualmin  
Package Updates module to install them selectively.


Should I update all packages?
