Subject: Stop setting hostname via kernel command line
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F4183%2Fhead;p=thirdparty%2Fmkosi.git

Stop setting hostname via kernel command line

This overrides the hostname from other sources, such as the nspawn
config file. Given we have DEFAULT_HOSTNAME= now, let's have users
use that and stop setting it explicitly ourselves.
