Hi everyone, I'm trying to get a full blown GNU distro of Linux running on my note pro but I've hit a snag. It seems like the device should support it, but every time I try to run a script that creates loopback devices, mounts directories, etc. I get permission errors even though I definitely have root.

Here's where it gets weird. Completel Linux installer fails when it tries to run this command:

Code: 
mknod /dev/block/loop255 b 7 255

and it gives this error:

Code: 
mknod: /dev/block/loop255: Operation not permitted

Despite what the error says, the script is being run as root. The app automatically opens the terminal and runs the command as root, but I also tried manually executing su and running the same script but the same error occurs.

As an experiment, I tried manually running just that one mknod commad and it works fine. In fact, if I manually execute every line in the bootscript.sh file it all seems to execute perfectly fine. But if I put the exact same mknod command into a .sh file and execute it like this:

Code: 
> sh test.sh

Then it gives the same error. Interestingly, if I directly run mknod as a non-root user it does not give me the "Operation not permitted" error, instead it says "Permission denied". I tried some other apps like Debian Kit as well and they seem to give the same error.

Any ideas why it would matter whether I manually enter a command into the terminal or whether I execute the same command indirectly from a file? I tried other terminal apps as well and it made no difference.

Thanks.

Good idea pheyx! That's a great workaround which basically solves my problem for now... or at least sends me on to the next problem :)

Thanks for you help.

I think I've found the reason. It's due to selinux. The selinux is set to enforced on android from 4.4. I flashed a kernel that sets selinux to permissive and it resolved the issue. Now the complete linux installer ran perfectly without modifying the scripts.

Yeah, how well is it running?

I guess it's out of the question both due to speed (Complete Linux Installer uses laggy VNC remote desktop) and hardware (I guess the stylus won't work pressure-sensitive-ish due to VNC), but I'd love to run MyPaint on NotePRO.

X Window performance is bad if using VNC, is better when using xsdl x server. Also can use fbdev(or fbturbo) native x server(and the cons is in either case must shutdown android stack),but I have no success using these two linux native x server
