817832 - fix media partition on android and b2g panda sdcards

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Jake Watkins [:dividehex]]

The Media partition, which has previously gone unused, is now being used for the panda android image.  In order for this to properly mount, it needs to be formatted in FAT instead of EXT4.  We need to change the Mozpool second stage script for both Android and B2G to properly format partition 6 (MEDIA).  In the android image, this is mounted by the vold auto mounting daemon as /mnt/sdcard.

Keep in mind, this does not mean we should be installing files to that partition during mozpool re-imaging (second stage).  We want to keep this process inline with typical android build output artifacts (eg. system data boot).  The /data partition is where bins and other files should be installed to be included with the android OS during installation.

we use this to store our testing data.  I am not really interested in anything else that might be stored on the /mnt/sdcard partition.

The squashfs will need mkdosfs installed in order for the second stage to format it correctly.

Do we need a similar change for b2g?

I don't believe so since b2g purposely mounts /mnt/sdcard to /data/media with fuse

I think it would be a good idea to change this for both b2g and android.  Even though b2g doesn't use this partition, this will keep it consistent.

landed.  We will also need to update all the active pxe configs to the new squashfs image.

[Dustin J. Mitchell [:dustin] (he/him)]

And once that's done, a puppet change to update config.ini:

[mozpool]
# this should correspond to a row in the pxe_configs table
b2g_pxe_config = panda-b2g.1

A new pxe config has been added as panda-b2g.2 which points to the new squashfs.
