Subject: [PATCH] Filesystem: Support symlink as mountpoint directory
Filesystem monitor operation fails when the `directory` attribute is a
symlink.
The monitor operation calls the `list_mounts` function, which cats
`/proc/mounts` if it exists, else cats `/etc/mtab` if it exists, else
runs the `mount` command. It then greps for `" $MOUNTPOINT "` in the
output, where `$MOUNTPOINT` is the value of the `directory` attribute.
`/proc/mounts`, `/etc/mtab`, and the `mount` command resolve symlinks
to their canonical targets. So while the monitor operation greps for
the symlink path (surrounded by spaces) as defined in the directory
attribute, the symlink will not be present in the `list_mounts` output.
Only the symlink's target will be present.
This patch uses `readlink -f $MOUNTPOINT` to resolve the symlink to its
canonical name before using it as a grep pattern in the
`Filesystem_status` function.
