And which physical card is that? Each time you boot? |

Yes, it is more complicated, but they are called predictable network |
23 |
names, not simple network names. It means you know exactly which port a |
24 |
network device refers to, every time you boot. Adding another NIC, even |
25 |
if it is discovered first, will not change the names of existing NICs. |

It's rather like the situation with hard disks, where sda may one day |
28 |
become sdb, so distros use UUIDs in fstab. UUIDs are far more cryptic |
29 |
than predictable network names, but no one complains loudly and |
30 |
pointlessly about them, which I can only attribute to provenance. |
31 |
|
32 |
Yes, the predictable names are pointless on a single-NIC system, which is |
33 |
why there exist simple methods to switch back to the old way. |
