Dears,
I'm studying the android 9.0 ramdisk mechanism
system-as-root is mandatory on android 9.0.
Assume:
1.use android9.0 + Kernel-4.4
2.system-as-root is enabled
3.here is a non-A/B scenario
Checking the soruce code:
*static int __init populate_rootfs(void)*
*{*
* char *err;*
* if (do_skip_initramfs) {*
* if (initrd_start)*
* free_initrd();*
* return default_rootfs();*
* }*
* err = unpack_to_rootfs(__initramfs_start, __initramfs_size);*
*......*
*}*
because the do_skip_initramfs is true and initrd_start is 0, just
default_rootfs is called.
Where is the system.img is verified and mounted? Do somewhere has the
detail flow process?
waiting for your good voice.
BestRegards
Andrew
