I’ve been messing around with using minirootfs as a base for lxc with s6. However, IPv4 connectivity doesn’t seem to work by default (not setting IP on interface). I was able to get it working by copying /usr/share/udhcpc/default.script from the main alpine lxc image.

The default config currently resides in busybox-initscripts which is not deployed on minirootfs since it has primarily been focused around Docker. After a brief chat with Natanael on IRC he said it might be better located in the busybox package. I agree in this case since minirootfs is targeted towards containers and LXC on Proxmox can be configured to use DHCP.
