Vault keeper has been around since Oreo, the RMM bypass zip disables it.but i dont have this symptom in pie S8+. debloating also is safe... but yeah, every phone restart, optimizing apps toast will appear. quiet annoying but still acceptable
regarding fstab, im curious if i adding "system" ==> /system in <mnt_point> , but i still worry if this could trigger the fault keeper thing or whatever that could brick the phone as informed in magisk thread.
I don't have any Pie devices and haven't had chance to examine any Pie firmware properly yet except for noticing that SYSTEM was mounted to ROOTFS.
This was a requirement introduced with Pie, however as ever Samsung seem to be doing their own thing and don't think the ramdisk has moved to system yet.
