Modular backuptool.sh. Executes backup and restore methods defined in arbitrary /system/addon.d/*.sh scripts. Tips & Tricks ============= * 50-cm.sh contains only a reference implementation. You may customize the methods however you wish. For example, 20-foobar.sh pre-backup can use a loop with conditionals to generate a dynamic backup list in /tmp/foobar_file_list which is later printed by list_files() so the backup method will act on those files. * Optional methods pre-backup, post-backup, pre-restore, or post-restore may be defined for special purposes. * Inject new files into /tmp/addon.d/ prior to backuptool.sh backup if you want to act during the current CM upgrade. * Delete files from /tmp/addon.d/ during post-restore if you want to permanently remove files from /system/addon.d/ Addons may use this approach to run a script only once. * Scripts run in sort -n order. Prefix with numbers 00 through 99 if want to run in a particular order. * You can have two separate scripts, implementing only backup in one, and only restore in the other with a different number prefix of each. This allows even greater control the backup/restore order even further. * You could use pre-backup to generate a one-time use backup script in /tmp/addon.d/ that deletes itself in post-restore. Patch Series ============ http://review.cyanogenmod.com/#change,13265 CyanogenMod/android_build * edify generator http://review.cyanogenmod.com/#change,13266 CyanogenMod/android_system_core * permissions on /system/addon.d http://review.cyanogenmod.com/#change,13267 CyanogenMod/android_vendor_cm * 50-cm.sh reference backup script * modular backuptool.sh * support backuptool.functions used by /system/addon.d/*.sh scripts Change-Id: Ifd5eaf9dcfd68d92e5043c21d1bae1dc0ad54860
