I'm just trying to get BB working with an /etc/network/interfaces file! I can't get ifup to properly edit the /var/run/ifstate file. > Fedora has it's (in)famous NetworkManager. I'm not too familiar with that. I don't want to add additional software other than what is present in BB to keep the size of the OS down. > I dealt with it by hooking necessary daemons into the service manager > I use, runsvdir. Presently I don't use runsvdir, but have it planned at some point in the future. > General idea is described here: > https://busybox.net/~vda/no_ifup.txt Looked at it, wouldn't this be the same thing as scripts in /etc/network/if-*.d directories? Plus using those directories with small scripts is modular instead of one big script as mentioned in the link that can quickly get out of hand. > Implementation details: some examples of my runsvdir setup are > in examples/var_service/* in busybox source tree.
