I ran across this app made by the dev that created voodoo sound and it was an app that protected your root after ota updates to your phone... Just wondering if anyone uses it and if it's compatible with the OE?

Root OTA Root keeper compatability?

If I remember correctly, one of the forum members tried this app in an attempt to preserve root when updating their Elite to ZV5. I don't think it actually worked, but perhaps they'll post here to confirm or deny that for you.
I tried the ota rootkeeper feature in the Superuser app and I can confirm that did not work to preserve root when I updated to ZV5. The su binary wasn't removed in the update, but its permissions were modified so that it was no longer functional. Rerooting was required.
The ota breaks the root when it does a recursive operation and changes permissions on all the executables in the /system/xbin directory. It also does this to /system/bin. You can place a suid binary in one of the directories that they don't recursively chmod and it will remain that way after the update.
Correct me if I'm wrong, but placing a copy of the su binary in another folder wouldn't help the situation, would it? A person wouldn't be able to move/copy it back to a bin folder without first having root access, correct?
