Subject: Add boot option pnet (Predictable Network Interface Names)
X-Git-Tag: v0.35.4~2^2
X-Git-Url: http://git.grml.org/?p=grml-live.git;a=commitdiff_plain;h=d56d6fa46055efde45399faa3a415a3b0a3bd9a8;ds=sidebyside

Add boot option pnet (Predictable Network Interface Names)

We plan to use Predictable Network Interface Names by default.

To make that switch easier we added a new boot option "pnet".

The kernel command line option "net.ifnames=0" is currently in every
boot option (except "pnet") but should be removed when Predictable
Network Interface Names works for us.

See: grml/grml#127
