[Asus Transformer TF700] elfaure:
Gotcha. OK results are in. No, it did NOT run from the command line! I mean it ran, but no browser mounts were created. It did NOT execute the script(s) in init.d

[Edit] Switched to superSU, same result.

u0_a87@android:/ $ mount | grep cache
/dev/block/mmcblk0p2 /cache ext4 rw,nosuid,nodev,noatime,errors=panic,user_xattr,acl,barrier=1,nomblk_io_submit,data=ordered 0 0
u0_a87@android:/ $ su
*** xyzzy 10087 happened ;) ***
u0_a87@android:/ # autostart4.sh

Multi-Browser2RAM startup script. This script must be run as root! This script can also run at boot.

This is a modified fork of Browser2RAM in sh script form. Only browser cache is mapped to RAM.
Browser data is persistent and is not lost after a reboot. Functions with 5 browsers: Stock, Naked,
Chrome, Opera Mobile, and Firefox. Also works with Boat and Dolphin.
