[Bug 1873907] [NEW] initramfs no dhcp because of 'Error getting hardware address for " en2s0": No such device'

[Thorsten Bonhagen]

Public bug reported:

kernel cmdline "ip=dhcp"

results in: 
Error getting hardware address for " en2s0": No such device
No network during boot

I have to change /usr/share/initramfs-tools/scripts/functions

fix:
run_dhclient() {
...
        dhclient -v -1 -cf "$conffile" -pf "$pidfile" "$@"
to 
        dhclient -v -1 -cf "$conffile" -pf "$pidfile" $@

regards
