Comment 12 for bug 1742971

From the machine running region/rack 10.244.40.30, we see the following:

1. /etc/maas/rackd.conf:maas_url: http://10.244.40.33/MAAS
2. /etc/maas/regiond.conf:maas_url: http://10.244.40.33/MAAS

The logs show this only for 1 machine, which correctly tells the machine to download the squashfs from the rack controller, and gives it the correct IP of the metadata URL, *but* removes the /MAAS for some reason, which effectively makes it invalid.

On the other hand, there are quite a few other logs that show that the URL is correct, with the same localtion for the images, and the correct URL for the metadata.

So somewhere in the code the /MAAS is being removed and we need to find out why.
