SE Linux file system relabel

[William Roberts <bill.c.roberts@xxxxxxxxx>]

I just stood SE Android up on a Maguro device. I have reviewed the patches submitted to the mailing list, but I would like to understand how to do some of this myself. I am trying to label the /factory files, currently the factory files are labeled as:

drwxrwxr-x radio    radio             u:object_r:unlabeled:s0 factory

I modified sepolicy/attributes and included this line:

#All types used for /factory files.

attribute factory_type;

 

I then created sepolicy/factory.te file that is this:

type factory, factory_type;

I then modified sepolicy/file_contexts to include

# factory files

/factory(/.*)?  u:object_r:factory:s0

I am trying to figure out how to label that part of the filesystem from scratch so I can understand the process a little better. Thanks for any help!
