    rc: improve dependencies for growfs
    
    Previously it depended on sysctl, which itself has no dependencies,
    so rcorder(8) had a bit too much flexibility when choosing when to run
    it.  Make sure it runs just between 'fsck' and 'root'.

+# Note that this uses awk(1), and thus will not work if /usr is on a separate

+# space on rootfs for the boot to succeed, and on images we ship - which are
+# the primary purpose of this script - there is no separate /usr anyway.
