 19  * for generating various files. Anything #define AID_<name>
 20  * becomes the mapping for getpwnam/getpwuid, etc. The <name>
 21  * field is lowercased.
 22  * For example:
 23  * #define AID_FOO_BAR 6666 becomes a friendly name of "foo_bar"
 24  *
 25  * The above holds true with the exception of:
 26  *   mediacodec
 27  *   mediaex
 28  *   mediadrm
 29  * Whose friendly names do not match the #define statements.

 31  * This file must only be used for platform (Google managed, and submitted through AOSP), AIDs.  3rd
 32  * party AIDs must be added via config.fs, which will place them in the corresponding partition's
 33  * passwd and group files.  There are ranges in this file reserved for AIDs for each 3rd party
 34  * partition, from which the system reads passwd and group files.
