Appears that growroot was running before /dev is mounted so the script
is unable to introspect the filesystem partition info. Run this after
all local filesystems are mounted to fix this issue.

We can resize the rootfs without the initrd based approach. Create a
growroot element which performs rootfs resizing as part of system init.
