I was able to find a fix for the problem:

(1) Edit /etc/default/voyage-util

   VOYAGE_SYNC_DIRS="var/lib/dhcp var/lib/logrotate"
   VOYAGE_SYNC_RECOVER_DIRS="var/lib/dhcp var/lib/logrotate"

(2) Stop the dhclient process.

   kill -s SIGTERM $(lsof / | awk '$4 ~ /[0-9].*w/ {print $2}')

(3) Recreate /var/lib/dhcp and /var/lib/logrotate (they must be 
directories, and empty; in my case one was a link to a non existent 
location and the other contained the DHCP lease file, effectively 
preventing a mount operation).

   rm -rf /var/lib/dhcp /var/lib/logrotate
   mkdir /var/lib/dhcp /var/lib/logrotate

(4) Reboot and check the output of the 'mount' command. It should show 
the root device as read-only and two additional mount points for the 
directories above.

The boot device is now read-only and the LEDs are working again.
