[Cialug] Auto create link in a folder

[Pixie]

This sounds like a perfect fit for a union mount for the staging
directory (see unionfs, aufs, overlayfs).

Something like:
  unionfs-fuse
/var/www/staging/wp-content/uploads-real=RW:/var/www/live/wp-content/uploads=RO
/var/www/staging/wp-content/uploads

(overlayfs may make more sense, depending on your kernel version.)
