When spamd isn't running as 'root', it cannot access the usual ~/.spamassassin
path where user-specific files normally reside. Instead, we use the path
/var/lib/spamassassin-<user> to store those home directories.
* Add group 'networkmanager' and implement polkit configuration
that allows users in this group to make persistent, system-wide
changes to NetworkManager settings.
* Add support for ModemManager. 3G modems should work out of the
box now (it does for me...). This introduces a dependency on
pkgs.modemmanager.
* Write NetworkManger config file to Nix store, and let the
daemon use it from there.
It specifies what mingetty will be stopped, if a bad filesystem
triggers an emergency shell.
That should be ttyS0 on headless systems, and in that case,
nixos should stop the ttyS0 mingetty from getting in.
I had some problems with LDAP user lookups not working properly
at boot. I found that invalidating passwd and group on the
ip-up event (when nscd-invalidate starts) helped a bit.
kernel 3.4+ needs cifs-utils to mount CIFS filesystems.
the kernel itself (and busybox's cifs mount code) are no longer able
to do this in some/most cases and will error out saying:
"CIFS VFS: connecting to DFS root not implemented yet"
Nixos' qemu-vm target is hurt by this, as it wants to mount /nix/store
via cifs very early in the boot process.
This commit makes sure the initrd for affected kernels is built with
cifs-utils if needed.
proxy_arp (and proxy_ndp for ipv6) can be turned on on a few
interfaces (at least 2).
This is mainly useful for creating pseudo-bridges between a real
interface and a virtual network such as VPN or a virtual machine for
interfaces that don't support real bridging (most wlan interfaces).
As ARP proxying acts slightly above the link-layer, below-ip traffic
isn't bridged, so things like DHCP won't work. The advantage above
using NAT lies in the fact that no IP addresses are shared, so all
hosts are reachable/routeable.
This especially annoyed me whenver I was doing nixos-rebuild switch and getting
logged out on all consoles. With this there now is services.mingetty.dontRestart
for heavy VT users to deactivate this behaviour.
