def _get_repack_usage():
return """Usage examples:
- * --ramdisk_add
+ * --ramdisk_add SRC_FILE:DST_FILE
- Specifies a list of files or src_file:dst_file pairs to copy.
- If --src_bootimg is specified, copy files from the ramdisk of --src_bootimg
- into the ramdisk of --dst_bootimg.
- If --local is given, copy files from the local filesystem into the ramdisk
- of --dst_bootimg.
+ If --local is given, copy SRC_FILE from the local filesystem to DST_FILE in
+ the ramdisk of --dst_bootimg.
+ If --src_bootimg is specified, copy SRC_FILE from the ramdisk of
+ --src_bootimg to DST_FILE in the ramdisk of --dst_bootimg.
+
+ Copies a local file 'userdebug_plat_sepolicy.cil' into the ramdisk of
+ --dst_bootimg, and then rebuild --dst_bootimg:
+
+ $ %(prog)s \\
+ --local --dst_bootimg vendor_boot-debug.img \\
+ --ramdisk_add userdebug_plat_sepolicy.cil:userdebug_plat_sepolicy.cil
+
+ Copies 'first_stage_ramdisk/userdebug_plat_sepolicy.cil' from the ramdisk
+ of --src_bootimg to 'userdebug_plat_sepolicy.cil' in the ramdisk of
+ --dst_bootimg, and then rebuild --dst_bootimg:
$ %(prog)s \\
--src_bootimg boot-debug-5.4.img --dst_bootimg vendor_boot-debug.img \\
--ramdisk_add first_stage_ramdisk/userdebug_plat_sepolicy.cil:userdebug_plat_sepolicy.cil
- The above command copies 'first_stage_ramdisk/userdebug_plat_sepolicy.cil'
- from the ramdisk of --src_bootimg to 'userdebug_plat_sepolicy.cil' of the
- ramdisk of --dst_bootimg, then repacks the --dst_bootimg.
+ This option can be specified multiple times to copy multiple files:
$ %(prog)s \\
--local --dst_bootimg vendor_boot-debug.img \\
- --ramdisk_add userdebug_plat_sepolicy.cil
-
- The above command copies a local file 'userdebug_plat_sepolicy.cil' into the
- ramdisk of --dst_bootimg.
-
- $ %(prog)s \\
- --src_bootimg boot-debug-5.4.img --dst_bootimg vendor_boot-debug.img \\
- --ramdisk_add first_stage_ramdisk/userdebug_plat_sepolicy.cil
-
- This is similar to the first example, but the source file path and
- destination file path are the same:
- 'first_stage_ramdisk/userdebug_plat_sepolicy.cil'.
-
- We can also combine both usage together with a list of copy instructions.
- For example:
-
- $ %(prog)s \\
- --src_bootimg boot-debug-5.4.img --dst_bootimg vendor_boot-debug.img \\
- --ramdisk_add file1 file2:subdir/file2 file3
+ --ramdisk_add file1:path/in/dst_bootimg/file1 \\
+ --ramdisk_add file2:path/in/dst_bootimg/file2
