/system being mounted rw while init.rc specifies ro

[spo...@gmail.com]

Hi All,

I am running into an issue developing a device based on Android ICS 4.0.4.   For some reason my system partition is always being mounted rw regardless of what the init.rc mount command says.

Here is the command in my init.xxxx.rc:
on fs
  mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/system /system wait ro

This appears to be the correct syntax and matches the implementation in the init.tuna.rc from AOSP.  However when I boot the device and execute mount I see the following:

/dev/block/platform/omap/omap_hsmmc.1/by-name/system /system ext4 rw,relatime,user_xattr,barrier=1,data=ordered 0 0

I've checked the rootdir init.rc file and the rest of my init.xxxx.rc to ensure that the partition is not being purposefully remounted rw anywhere along the way.

What could cause the system partition to be mounted rw regardless of the init command?

Thanks,
SP

Thanks Michael,

This got me pointed in the right direction and I was able to adjust the SGX code to behave properly for our device.
