есть у меня сервер с CentOS 6 с доступом только по ssh, и хочется на него установить что-нибудь по свежее. Доступ к IPMI тоже есть, только логин-пароль от IPMI я не знаю. Хочу через debootstrap установить Debian Stretch (самое свежее, что может работать с ядром 2.6.32). Т.к. reboot можно сделать только единожды, я начал тренироваться на кошках.
Взял второй компьютер, установил CentOS 6, включил sshd, подвинул LVM разделы, создал новый, через debootstrap установил туда chroot окружение для debian stretch, в нём всё вроде настроил, установил ядро 4.9.0, настроил grub, загружаюсь в debian, а там нет сети.
# ip link show
1: lo: ....
2: enp2s0: ....
ОК, исправляю /etc/network/interfaces c
source-directory /etc/network/interfaces.d
auto eth0
iface eth0 inet dhcp
на
source-directory /etc/network/interfaces.d
auto enp2s0
iface enp2s0 inet dhcp
всё работает.
Но проблема в том, что понять, что eth0 это enp2s0 надо как-то в centos или в chroot-debian. Пробую:

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

и что-то ни каких намёков на enp2s0. Или я чего-то не вижу?
Чат GPT говорит, что «p2s0 или s33 — указывают на номер порта или слот на материнской плате»
