[SOLVED] Can's start netctl via systemd

[71GA]

Hello, I am trying to start/enable my eth0 interface via the systemd. I put my profile named eth0 in the /etc/netctl folder and it looks like this:
$this->bbcode_second_pass_code('', 'Description='Povezava Raspberry PI z namiznim racunalnikom'
Interface=eth0
Connection=ethernet
IP=static
AutoWired=yes
Address=('169.254.39.201/16')
Gateway=('169.254.39.200')
DNS=('193.2.1.66' '193.2.1.71')')
I then disabled/stopped systemd-networkd.service and enabled/started netctl.service. Now the weird stuff comes in. Everything is fine if I start netctl interface using command:
$this->bbcode_second_pass_code('', 'netctl start eth0')
This command brings up eth0 interface and assigns it a correct IP address. I can check this using ifconfig:
$this->bbcode_second_pass_code('', 'eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 169.254.39.201 netmask 255.255.0.0 broadcast 169.254.255.255
inet6 fe80::ba27:ebff:fe15:8ec9 prefixlen 64 scopeid 0x20<link>
ether b8:27:eb:15:8e:c9 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 55 bytes 4098 (4.0 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0')
Then I stop this interface using stop instead of start. Once eth0 is stopped I try to start it using systemd:
$this->bbcode_second_pass_code('', 'systemctl start netctl-ifplugd@eth0.service')
Command executes ok, but when I check the services using systemctl command, I can see that service did not start like it should. Furthermore there are more netctl interfaces:
$this->bbcode_second_pass_code('', '* netctl-ifplugd@eth0.service loaded failed failed Automatic wired network connection using netctl profiles

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.

85 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.')
Can anyone tell me, what am I doing wrong?

You never tried systemctl enable netctl@eth0
systemctl enable netctl-ifplugd@eth0 should have been goo too
Note first case actually refers to the filename, second case (ifplugd) all files where Interface=eth0

[71GA]

Command:
$this->bbcode_second_pass_code('', 'systemctl start netctl@eth0')
works and this is what I needed. But on the other hand command:
$this->bbcode_second_pass_code('', 'systemctl start netctl-ifplugd@eth0')
does not work. Why is that? Is package ifpluggd even included in the installation file?

ADD:

What kind of a symbolic link do I have to create in order to achieve same results as with command?
$this->bbcode_second_pass_code('', 'systemctl enable netctl@eth0')

[pepedog]

If you disable and enable again, it will tell you all the symlinks made.
I don't know why ifplugd doesn't work, it used to be very reliable.

[71GA]

Oh sorry I corrected my reply above. Command:

$this->bbcode_second_pass_code('', '
systemctl start netctl@eth0
')

works, but I need to allso enable it at boot, so I allso need command:

$this->bbcode_second_pass_code('', '
systemctl enable netctl@eth0
')

to work. But it doesn't. It returns an error:

$this->bbcode_second_pass_code('', '
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
')

which is weird, because this is a fresh install of Archlinux-ARM.

$this->bbcode_second_pass_quote('', 'I')f you disable and enable again, it will tell you all the symlinks made.

Sorry, it should be
netctl enable eth0
Wiki is marvellous https://wiki.archlinux.org/index.php/Netctl

$this->bbcode_second_pass_quote('', '
')Sorry, it should be
netctl enable eth0

netctl has interfacing to systemd. Simply `netctl enable eth0` `netctl start eth0` would have done it.
