This one has me really stumped.

I upgraded my kernel and all networking devices vanished. No problem, I thought.
I booted to the old kernel, but they were gone there too! Even lo was gone!

Booting to the previously working kernel, "ifconfig" yields nothing, although "ifconfig -a" shows both enp0s10 (aka eth0) and lo.

Trying /etc/init.d/net.lo gives a strange error message:

#/etc/init.d/net.lo start
* bringing up interface lo
/etc/init.d/net.lo: line 585: _exists: command not found
* ERROR: Interface lo does not exist
* Ensure that you have loaded the correct kernel module

So what happened to the "exists" routine? What have I hosed?

revdep-rebuild showed nothing odd
dmesg seems fine, showing both the local and local interfaces as expected

Obviously, I corrupted some basic system file, but I'm darned if I can figure out which one.

Anybody got any ideas?

TIA!

Try re-emerging openrc ?

Re-emerging openrc did the trick.


Thanks!

What about putting a "[solved]" in front of the topic ? ;)

Hmmmm... this is getting weird.

It worked ONCE, then gives the same eror.

I've re-emerged openrc, sysvinit, and baselayout. I still get the same error.

However, now the lo device is present. the command iconfig shows it to be up and running, but no ethernet.

# ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536


Anybody got any ideas?

I hate to rebuild the entire system again. (Actually, I love to do it, but I hadn't planned to this weekend)

What version of each are you using? (emerge --info)

Have you emerge --sync'ed lately?

I was looking at my net.lo script and it doesn't appear to be the same as the one you have...

emerge --info please? I haven't hit the bug yet so curious what versions of openrc, sysvinit, etc. you are using...

EDIT: Never mind, I did this to myself. I'd keyword accepted =sys-apps/openrc-0.12, which meant that when it dropped out of the tree, I accidentally downgraded to openrc-0.11.8 which caused breakages! And for the record, net.lo is provided by net-misc/netifrc now. I'm not sure what actually provides net.lo for <openrc-0.12 though. I think openrc should provide it, so there might be a bug in stable here. My system is alive again, so that's all that matters to me!

**Original Post**
Did anyone find a solution for this? It happened with the most recent update to openrc. Kernel hasn't changed, I'd already been through the udev migration and that went fine (I'd stuck with the old net names, but in the process of trying to fix this migrated to the new net names). I'm thinking maybe an old net.lo script? But I don't know what package net.lo comes from any more. I would have assumed baselayout but it seems not.

I've tried re-emerging openrc, sysvinit, baselayout and udev to no avail.

Here's what attempting to start net.lo says:
Code:
 * Bringing up interface lo
/etc/init.d/net.lo: line 558: _exists: command not found
 *   ERROR: interface lo does not exist
 *   Ensure you have loaded the correct kernel module for your hardware
 * ERROR: net.lo failed to start


Interfaces definitely exist. ifconfig:
Code:
