I know I can switch to systemd - since Gnome 3.8 (to my great
disappointment) forcefully pushes users to move on, but the unit files are
still lacking. One mentionable example is iptables. No iptables unit file.
I may (or might) have enough time for this by the end of the year.

BTW: any of you ever operated a machine with bonding using systemd? I've
found no documentation regarding the official way to achieve that. I'm
curious before I start hacking in my non-professional way.

Thanks:
Dw.

I should probably have emailed the list to warn people about 3.0. It is
fresh off the assembly line and there are issues. I hit one myself but
didn't report it yet because a new release just came out.

I will not stabilize a 3.0 anytime soon. Please use a 2.9.1 of the time
being:

1) any 2.6.32

2) <= 3.2.52-r6

3) <= 3.11.9

Currently the tree has only 2.9.1. The overlay has 3.0.

Thank you Toth for pushing that report upstream.

Bonding is supported by net-misc/netctl. Also, this functionality will
be in systemd itself in the future (systemd-networkd).

Thanks for pointing to that email. Now I have a feeling again, that
systemd is not ready for production purposes. Although it's not on the
TODO list, I hope it will get there soon...

I will refrain from using this new version of 3.0 grsec+gradm.
But will give it a try when a new version comes out, anyways.

I have to also prepare to invest some energy into connection tracking
helper assignments.

Just to let you know:
I've retested gradm-3.0 using hardened-sources-3.12.4 and the system seems
to behave.
Reloading policy no longer renders the machine unresponsive.
Log messages related to user mode helper binary have also gone.

Regards: Dw.
