In slow networks like Infiniband it takes much time for the interface to get the carrier. This patch enables this service to run more then 20 seconds and limited by DIB_DHCP_TIMEOUT. Change-Id: I8a6015567ac25e37b5a5aba4b1fda71170cc144a

dhcp-all-interfaces
|
|
===================
|
|
Autodetect network interfaces during boot and configure them for DHCP
|
|
|
|
The rationale for this is that we are likely to require multiple
|
|
network interfaces for use cases such as baremetal and there is no way
|
|
to know ahead of time which one is which, so we will simply run a
|
|
DHCP client on all interfaces with real MAC addresses (except lo) that
|
|
are visible on the first boot.
|
|
|
|
On non-Gentoo based distributions the script
|
|
/usr/local/sbin/dhcp-all-interfaces.sh will be called early in each
|
|
boot and will scan available network interfaces and ensure they are
|
|
configured properly before networking services are started.
|
|
|
|
On Gentoo based distributions we will install the dhcpcd package and
|
|
ensure the service starts at boot. This service automatically sets
|
|
up all interfaces found via dhcp and/or dhcpv6 (or SLAAC).

|
DIB_DHCP_TIMEOUT
|
|
:Required: No
|
|
:Default: 30
|
|
:Description: Amount of time in seconds that the systemd service will
|
|
wait to get an address. Should be increased in networks such as Infiniband.
|
|
:Example: DIB_DHCP_TIMEOUT=300
