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

22 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.
26
27 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.
