initscripts: populate-volatile: suppress read-only-rootfs warnings
rm: can't remove '/etc/resolv.conf': Read-only file system ln: /etc/resolv.conf: File exists /etc/default/volatiles contains an entry: l root root 0644 /etc/resolv.conf /var/run/resolv.conf which causes populate-volatile.sh to execute the following in link_file(): if [ -L \"$2\" ]; then [ \"\$(readlink -f \"$2\")\" != \"\$(readlink -f \"$1\")\" ] && { rm -f \"$2\"; ln -sf \"$1\" \"$2\"; }; elif [ -d \"$2\" ]; then ... At the time the image is created, /etc/resolv.conf is already a symlink to /var/run/resolv.conf, but at boot time when populate-volatiles.sh is run, /var/run/resolv.conf doesn't exist, causing it to try to rm -f and ln -sf which of course fails due to the read-only filesystem.
