Ubuntu Server (and others) If you play a lot with servers or networked PCs with multiple NICs and change and switch network cards often, you sooner or later end up with two computers having network cards named in a different order by the operating system (eg. the NIC in the first slot is eth0 on one computer while being eth1 on the other). But usually you want to have all computers in a group configured the same way
Platform: Ubuntu Server When we access a machine remotely over SSH, we sure do not want its daemon to crash and leave us without the means to access the system. So what we want is some means to make sure that the daemon is immediately restarted in the case of such an unfortunate event.
