The logic is: 1. Generate name-id pairs required by droid layer to droid.ids. 2. On installation create all the required user and groups and note their names and ids to droid.ids.created. 3. On update cross-check the two files and only add and remove the name-ids that have been changed. ad. 1. usergroupgen.c no longer creates shellscript output, instead it creates droid.ids which is a simple text file with name-space-id format, one per line. ad. 2. postinstall script writes down every name-id it managed to create. It does not write any user creation of which failed. ad. 3. it is not verified during user/group removal if the user/group was modified by the user or with a third-party script. If the entry disappeared from droid-hal, we just remove it. Special note: A conversion mechanism was added for upgrades from previous dhd releases in the preinstall script. All users that were added in the previous release are considered to have been created. Change-Id: I2a13462bed5297f3c4ef601fcd26194c59444a3f
