From: Martin Hundebøll <[email protected]> When the populate-volatile.sh initscript tests if a configured symlink is already in place, it uses readlink with the '-f' (follow) option:
> [ "$(readlink -f $source)" = "$dest" ] If the test fails, it proceeds to delete the exisiting folder/file, and create the configured symlink. However, the '-f' option to readlink makes it follow symlinks pointing at symlinks. If the $dest argument is a symlink, the above test fails, and warnings are printed due to changing a read-only rootfs. This is the case for /tmp, and /etc/resolv.conf: > /tmp -> /var/tmp -> /var/volatile/tmp > /etc/resolv.conf -> /var/run/resolv.conf -> /run/resolv.conf Fix the warnings by removing the '-f' option, so that the test matches the configuration.
