Previously, k3s.service was failing when the EnvironmentFile does not exist:
```

[systemd] really wait for network to come online (#1665)
Wants= is required to actually set the dependency on network-online.service
After= is required or k3s.service will be started at the same time as network-online.service

In network environments with slow DHCP, both are required to ensure valid network configuration for k3s

b4335630b7 [systemd] Add value to LimitNOFILE due to performance problems
When k3s is installed on an OS with default high ulimits, performance
issues can be observed. This was discovered on CoreOS where the default
value is 1073741816. Symptoms include very slow file operations such
as installing a Rook/Ceph cluster will take ~6 hours instead of ~10 minutes.

A google search for 'container LimitNOFILE' will show that most major
projects set this already, including the (unused) containerd systemd unit
found in this repository at /vendor/github.com/containerd/containerd/containerd.service

k3OS is not affected becuasse the default there is already 1048576.

See description in coreos/fedora-coreos-tracker#329

f9dd8dedc8 Add a little extra delay between restart attempts
This extra delay prevents systemd from determining that the service is restarting "too quickly".

f7e0017fed Extend systemd start timeout for slow systems
Cert generation may cause slow startup times for some systems such as
the Raspberry Pi, set the systemd service TimeoutStartSec to Infinity to
avoid startup timeouts.
