We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
Format:
bond=<bondname>[:<bondslaves>:[:<options>]]
bondslaves is a comma-separated list of physical (ethernet) interfaces.
options is a comma-separated list on bonding options (modinfo bonding for
details) in format compatible with initscripts.
If options include multi-valued arp_ip_target option, then its values
should be separated by semicolon.
bond without parameters assumes bond=bond0:eth0,eth1:balance-rr
The manpage for dhclient-script says:
Before actually configuring the address, dhclient-script should
somehow ARP for it and exit with a nonzero status if it receives a
reply.
By using arping in dracut this is very easy, since arping has a
specific option to do just that.
This patch adds STP timeout error handling with arping. It's rather
simple since it only cares about the primary interface and blindly
assumes that if no gateway is available the root server is on the
same subnet.
The usual approach to setting mtus is to set the interface down,
set the mtu then set the interface back up again. Modern hardware
and/or drivers may support setting this on the fly, so we try
this and fall back to the old behaviour it it doesn't work.
In addition this patch only allows mtus greater than 576, this is
taken from debian/ubuntu dhclient-script.
ifname=<interface>:<MAC>
Assign network device name <interface> (ie eth0) to the NIC
with MAC <MAC>.
Note that if you use this option you *must* specify an ifname=
argument for all interfaces used in ip= or fcoe= arguments
ifname=<interface>:<MAC>
Assign network device name <interface> (ie eth0) to the NIC with MAC <MAC>.
Note that if you use this option you *must* specify an ifname= argument
for all interfaces used in ip= or fcoe= arguments
This introduces filter_kernel_modules, which should be used to install
all kernel modules that match whatever criteria you want.
If running in --hostonly, filter_kernel_modules will only consider
modules that are loaded in the kernel, otherwise it will consider
all the modules installed on the system for the appropriate kernel.
This drastically reduces initramfs generation time when using --hostonly
by eliminating lots of unneeded filesystem activity.
