Currently interfaces(5) says in KNOWN BUGS/LIMITATIONS:
Unfortunately it can happen that the kernel assigns different physical
interface names to the same hardware at different times; for example,
what was called "eth0" last time you booted is now called "eth1" and
vice versa. This creates a problem if you want to configure the
interfaces appropriately. A way to deal with this problem is to use
mapping scripts that choose logical interface names according to the
properties of the interface hardware. See the get-mac-address.sh
script in the examples directory for an example of such a mapping
script. See also Debian bug #101728.
The modern solution, described in Debian docs [1], is to use edit /etc/udev/rules.d/70-persistent-net.rules. I suggest we stop talking about confusing get-mac-address.sh script and instead replace the last two "See…" sentences with:
See /etc/udev/rules.d/70-persistent-net.rules for a way to set interface names persistently.
I realize that Debian docs is linked at the end of this man page. But it's not clear it will help with consistent names problem, because KNOWN BUGS says get-mac-address.sh is needed for this. Let's help people that are new to all these things :-)
