We should actually start counting from the parent directory and not from the symbolic link as it will represent a wrong count of hops from the actual mountpoint. The symlinks in /sys/dev/block and /sys/dev/char worked only by luck, because I have set it to the wrong parent directory which is the /sys/dev directory, so with the symlink it was 3 hops to /sys, together with the root directory, therefore, everything seemed to work. Now that the device symlinks in /sys/dev/block and /sys/dev/char are set to the right parent directory and we start measure hops from root directory with the parent directory of a symlink, everything seem to work correctly now.
