On my project I need to track filesystem changes inside a container from the outside. In Linux this can be done by tracking /proc/<pid>/root path. Since we are in /proc filesystem, we have "special" symlinks.
lrwxrwxrwx 1 root root 0 Jan 7 01:51 root -> /
It points to / root, which is not host's root. Notify follows this trap and watches host's root instead of /proc/<pid>/root/... path.
My suggestions:
Option to disable the ability to follow symlinks.
Option (or permanent solution) to disable the ability to follow symlink on path itself, which is passed to notify.Watch()
....?
For now, I just comment out canonical function in cleanpath, but it is just temporary solution.
