/usr inappropriately soft-links to /: Results in infinite recursion with, "ls -lR /"

Description

If you go to the root of the file-system in Redox and enter the command, ls -lR (or simply type, ls -lR / anywhere) it goes into infinite recursion showing files/folders in:

/usr/bin /usr/usr/bin /usr/usr/usr/bin ... /usr/usr/usr/.........../usr/bin etc.

Environment info

Inside Redox OS running under QEMU following the proscribed procedures.

  • Operating system:

Ubuntu 17.04 (Linux)

  • uname -a:

Linux butler-Leopard-Extreme 4.10.0-38-generic #42-Ubuntu SMP Tue Oct 10 13:24:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

  • rustc -V:

rustc 1.23.0-nightly (79cfce3d3 2017-11-12)

  • git rev-parse HEAD:

5f7233417b7934604ac5e355989dd4613c1b64c5

Steps to reproduce

  1. Build Redox
  2. start it with, "make qemu"
  3. Login using "root/password"
  4. enter the following command, "ls -lR /"
  5. watch as it infinitely recurses into /usr, /usr/usr, /usr/usr/usr, ...

Behavior

  • Expected behavior:

    • lists all files/folders on the file-system without infinitely recursing

  • Actual behavior:

    • infinite recursion into /usr, /usr/usr/, ...

  • Proposed solution:

    Change /usr to be an actual folder and /usr/bin to be a soft-links to /bin as follows:

rm /usr
mkdir /usr
chown root:root /usr
chmod 755 /usr
ln -s /bin /usr/bin

EDIT: Make the sub-folders of /usr that are soft-links correctly reflect the desired/current folders at the / level in RedoxOS
