Public bug reported:
[Impact]
To support the previous behavior with ipconfig, dhclient now ships a config
script for the initramfs which is meant to write out /run/net-(interface
name).conf, which may be read by later initramfs scripts to configure a remote
rootfs or other networked features. Data for both IPv4 and IPv6 are written out
to the same file, which can lead to confusion and incorrect behavior.
[Test case]
1) Boot a system with an iscsi rootfs on a network where no DHCP server answers.
Current behavior:
dhclient -6 results may be written out to the /run/net-$iface.conf file which
would cause the boot process to continue, thinking it's done.
Expected behavior:
boot should only continue once a network is found (through DHCP, BOOTP, etc.).
[Regression potential]
This changes is not expected to cause any kind of regression. Use of isc-dhcp
has been reverted in initramfs-tools, and as such the affected code paths would
not be run.
