Kernel: Implement bind mounts
You can now bind-mount files and directories. This essentially exposes an existing part of the file system in another place, and can be used as an alternative to symlinks or hardlinks. Here's an example of doing this: # mkdir /tmp/foo # mount /home/anon/myfile.txt /tmp/foo -o bind # cat /tmp/foo This is anon's file.
