Correct. Using a statically linked qemu does not require me to have /host-rootfs bind mounted which is why I prefer static qemu over dynamic qemu. > I'd prefer not to introduce a new command-line option for this purpose. > Instead, the "/:/host-rootfs" binding could be added to the list of > recommended bindings (-Q/-B options) and PRoot could detect automatically > where the host rootfs is bound, no matter where it is.

You didnt make it explicit but if your proposal includes removing the implicit bind mounting of /host-rootfs when qemu user mode emulation is activated, then it completely solves my problem. > I could implement this feature in the next release of PRoot if you wish > (v3.2).

I was trying to use proot to create a foreign architecture rootfs while I used fakeroot/fakechroot before. My only problem with proot was that it fake-bind-mounted /host-rootfs into the foreign system. This led to tools like find, tar, du, grep etc (everything that recursively walks a directory tree) which were supposed to work on the whole foreign rootfs also work on my host fs. While some of the tools like find and tar allow me to exclude certain subdirectories, it is harder to work around this issue with other tools. So while before the tools could assume that everything within that foreign rootfs directory is indeed only the foreign rootfs, I now have to manually exclude /host-rootfs *somehow*. And before I start implementing the required workarounds I wanted to see if this could not be changed in proot instead.
