- starting with Pixel 7 series, boot_img_hdr_v4 is now even more complicated, adding 2 more new partitions (init_boot and vendor_kernel_boot) so let's attempt to keep it as simple as we can
- if init_boot partition is detected split up flash files for boot (kernel), init_boot (ramdisk), and vendor_kernel_boot (dtb)
- continue to support current practice of Image* and dtb in zip root by automatically creating a multi-partition AK3 zip setup from these files (ramdisk directory is for the init_boot partition since that's where Magisk and overlay.d will be)
NOTE 1: anykernel.sh must still be setup for multi-parition patching - see the updated Example file for parts to uncomment
NOTE 2: currently magiskboot still does not support unpack/repack of VNDRBOOT v4 multi-ramdisk format (i.e. vendor_boot v4 and vendor_kernel_boot) so if modifications are necessary in these ramdisks they will need to be prebuilt and flashed whole by including vendor_boot.img and/or vendor_kernel_boot.img in the zip root
- both boot for kernel and init_boot for first stage ramdisk access to overlay.d will be needed
- remove ramdisk and recovery_ramdisk from detection since devices which use them also use kernel partition and would need to be multi-partition setups either way
- exclude "zimage" as a compression type since magiskboot unpack, split and repack handle it automatically and there is no fallback
- ensure $comp is a working command for all busybox compression fallbacks
- some devices fail to boot when magiskboot changes the vbmeta flag is set in the AVBv2 signature from 00 to 03, this allows disabling that behavior
- set keep_vbmeta_flag=1 in anykernel.sh to force it to keep whatever's there, =auto will take it from the existing image if Magisk-patched (Canary 23016 or later), and =0 will allow the default magiskboot behavior
- fix duplicate kernel version (vertmp) entries from some kernels
- don't use head when grep -m1 will suffice
- fix some (bad) OEM prop files including entries twice, use last entry like live system
- adds partial hdr v4 support (cannot currently unpack vendor_boot v4 multi-ramdisk or bootconfig)
- use upstream CI build since it includes an AVBv2 signature padding fix, resolving all known regressions
Closes#61
- attempt to mount other partitions whether determined as /system or /system_root
- /system_root by that point if mounted will actually be /system_root so no need for further checks
- add missing /system_ext entries to custom getprop and cleanup functions
- boot_img_hdr_v3 now has dtb stored in a new partition called vendor_boot
- allow block=vendor_boot partition detection
- support current practice of Image* and dtb in zip root by automatically creating a multi-partition AK3 zip setup from these files (ramdisk directory is assumed to be for the boot partition)
- fix reset_ak current files cleanup
- unpackbootimg/unpackelf kernel+ramdisk suffixes were corrected to match their corresponding mkbootimg argument in my latest forked tools (AIK-mobile v3.8)
- fix repack from unpackelf to mkbootimg broken base value introduced with AK3 rewrite
- touch up a couple pesky minor things
- add global scope to replace_line and remove_line so they match replace_string, and can now work on all matches found in a file
- remove unnecessary slot swapping since this is already handled with $POSTINSTALL and FlashAfterUpdate addon.d-v2's setup
- add cache mounting into main functions
- rename slot function to bring in line with my other projects
- don't rely on props if possible: determine dynamic/logical partitions from /dev/block/mapper presence, and detect slots more robustly using props and cmdline as in AK3 Core
- fix opposite slot detection for pushing modules to system and/or vendor during addon.d-v2
- fix naming BootSignature_Android.jar -> boot_signer-dexed.jar for my own builds (see https://issuetracker.google.com/issues/143810860)
- correct unpackbootimg/unpackelf suffixes which now correspond to their matching mkbootimg argument
- only do setup_env and restore_env when in recovery to prevent environment/mount issues post-install
- use busybox [ for simple integer test to ensure known numerical operator behavior
