After updating BIOS, my network interface name changed from
enp5p0, but whyyyy?! It's like ... stupid. Everything stopped working - firewall changed zone to default "public" which has everything blocked; pi-hole stopped accepting dns requests from external devices. everyone was angry because "net was down" (because dns didn't work).
It's not like network card MAC or hardware or anything changed, it did not. Why did Manjaro decide to change the name in the first place?
yees... got it fixed with applying udev rule to rename/force_name it back to
enp24p0 and everything went back to normal, but initially realizing what's wrong in the first place (the initial random name change itself) took like 30m at least (because most of stuff on the computer itself was working fine, just some external services failing) and another 15 to find solution and apply it...
