Hi, i testing rolling version of vyos 1.20. In 1.1.8 version, i use enable script like this:
echo “options ixgbe allow_unsupported_sfp=1” > /etc/modprobe.d/ixgbe-options.conf
depmod -a
update-initramfs -u
reboot
this script in 1.20 not working .
error is I: update-initramfs is disabled (live system is running without media mounted on /lib/live/mount
/medium)
any idea to enable sfp + ? 
thank you
Bohous
