how can I mount nfs without into recovery mode by set cmdline manually

./mkbootimg {MKBOOTARG} --cmdline "{cmdline}" > /dev/null 2>&1
I found this,is that right?

are you like to mount nfs
or to mount nfs in order to boot or flash from it?

mount nfs in order to boot or flash from it

weren’t you able to achieve it in the other thread?

./flash.sh --no-flash -k kernel-dtb -n 192.168.1.123:192.168.1.100:192.168.1.1:255.255.255.0 -N 192.168.1.100:/home/red/nfsroot
