Ok, If you are going to be running a Kexec Rom, or one that's going to be including any custom kernel than you must first going into Safestrap and toggle back to your nonsafe side. (your stock, rooted system). Then install Safestrap 2.11 in there, this way it carries over to whatever rom you run, including custom kernels on your safeside. Just installed 2.11 within you safeside rom won't work because once you format your system, SS 2.11 disappears with it. Hope that helps
OK. Well, it's been a while since I read about it but it seems to me that the way Hashcode explained it, safestrap gets installed to the preinstall folder. The preinstall folder isn't a subfolder of the system folder so it seems to me that it should work fine regardless of whether it's installed on the safe side or the nonsafe side. Also, I seem to remember seeing where Hashcode said it could be installed on either side. I'm going to give it a try sometime this weekend and find out the hard way I guess.
Now that I think about it, mine is installed from the safe side and I've installed a couple roms since I installed it that way. Formatted /system both times and it worked fine. Is there something diffferent about a Kexec rom from a non Kexec rom? Seems to me that formatting the system partition is formatting the system partition regardless of what rom you're going to install. Anyway, I'm not trying to challenge you in this, it's just that I'm somewhat confused now. So, have to ask.
Whatever the case, I'll be a guinea pig for everybody. Sometime in the next day or two I'll give it a try. Unless I hear the world will come to an end if I do.
