Keep-root Recovery for Motorola Droid

If you currently have root access on your Motorola Droid but are running a vanilla (not custom) ROM, you need to take precautions when applying an OTA update. By default an OTA update will remove your root access. Some phones are rather easy to re-root (for instance, Nexus One), but in some cases the OTA update patches up the security holes exploited to gain root access.
My remedy is shsu -- a very simple patch on top of the standard recovery image that will prevent loss of root access when applying an OTA update. Here's how to install and use it: read more

An OTA update typically removes the setuid bit from all executables on the system partition (the only one allowed to have the setuid bit set). To avoid losing root, I crafted my own recovery image which differs from the vanilla recovery image in one major aspect: before it reboots, it installs shsu: a shell-only su. Thus, even after unintended OTA update (happened before), I keep my root access.
