Currently runqemu hardcodes the "ip=" kernel boot parameter
when configuring QEMU to use tap or slirp networking. This makes
the guest system to have a network interface pre-configured
by kernel and causes systemd to fail renaming the interface
to whatever pleases it:
Feb 21 10:10:20 intel-corei7-64 systemd-udevd[201]: Error changing
net interface name 'eth0' to 'enp0s3': Device or resource busy,
Always append user input for kernel boot params after the ones
added by the script. This way user input has priority over runqemu's
default params.
