| # This is an example post-install script. This script will be executed by the |
| # update_engine right after finishing writing all the partitions, but before |
| # marking the new slot as active. To enable running this program, insert these |
| # lines in your product's .mk file (without the # at the beginning): |
| |
| # AB_OTA_POSTINSTALL_CONFIG += \ |
| # RUN_POSTINSTALL_system=true \ |
| # POSTINSTALL_PATH_system=bin/postinst_example \ |
| # FILESYSTEM_TYPE_system=ext4 \ |
| |
| # This script receives no arguments. argv[0] will include the absolute path to |
| # the script, including the directory where the new partition was mounted. |
| # |
| # The script will run from the "postinstall" SELinux domain, from the old system |
| # environment (kernel, SELinux rules, etc). New rules and domains introduced by |
| # the new system won't be available when this script runs, instead, all the |
| # files in the mounted directory will have the attribute "postinstall_file". All |
| # the files accessed from here would need to be allowed in the old system or |
| # those accesses will fail. For example, the absolute path used in the first |
| # line of this script (/system/bin/sh) is indeed the old system's sh binary. If |
| # you use a compiled program, you might want to link it statically or use a |
| # wrapper script to use the new ldso to run your program (see the |
| # --generate-wrappers option in lddtree.py for an example). |
| |
| my_dir=$(dirname "$0") |
| |
| echo "The output of this program will show up in the logs." >&2 |
| echo "Note that this program runs from ${my_dir}" |
| |
| # If the exit code of this program is an error code (different from 0), the |
| # update will fail and the new slot will not be marked as active. |

| exit 0 |
