Running from tmpfs

Hi!

I'd like to know if LTP tests can be run entirely from tmpfs? My system has rootfs mounted read-only, and I would like to avoid remounting it. Do you have tests that require write access to rootfs?

I've succeeded in running the runltplite.sh set of tests from tmpfs, but to accomplish this with runalltests.sh minor modifications to the script is required.

So, I started wondering, is the limitation because of inherit properties of the tests, or just poor paramerization of the script.

Thanks!

Not for writing, there were some buggy tests that utilized / directly but that should have been fixed (at least I hope so). If you find such testcase it's considered a bug.

I would say poorly written script, and as usuall patches are welcome ;).
