That did it! The
DEVICE=eth0
in ifcfg-eth0 did it. I didn't have that in my (automatically generated)
ifcfg-eth0. Once I added that it worked. Matlab is now up and running!
Thank you very much!
On a final note, net.ifnames=0 works in conjunction with
/usr/lib/udev/rules.d/80-net-name-slot.rules:
cat /usr/lib/udev/rules.d/80-net-name-slot.rules
# do not edit this file, it will be overwritten on update
ACTION!="add", GOTO="net_name_slot_end"
SUBSYSTEM!="net", GOTO="net_name_slot_end"
NAME!="", GOTO="net_name_slot_end"
IMPORT{cmdline}="net.ifnames"
ENV{net.ifnames}=="0", GOTO="net_name_slot_end"
NAME=="", ENV{ID_NET_NAME_ONBOARD}!="", NAME="$env{ID_NET_NAME_ONBOARD}"
NAME=="", ENV{ID_NET_NAME_SLOT}!="", NAME="$env{ID_NET_NAME_SLOT}"
NAME=="", ENV{ID_NET_NAME_PATH}!="", NAME="$env{ID_NET_NAME_PATH}"
LABEL="net_name_slot_end"
If this rule is shadowed by a custom rule in /etc/udev/rules.d, then
obviously net.ifnames=0 has no effect. But the custom rules should take
care of it. You didn't have any custom rules, so net.ifnames worked as
expected. I removed all my custom rules in /etc/udev/rules.d. DEVICE=eth0 was
what I was missing though.
