[Samba] deleting symlinks only

thank you, kurt
well, maybe for most application this workaround would work. But from
the unix-point of view replacing a symbolic link with a windows-link is
like replacing a car with a donkey... Why should someone create a
symlink on a sambaserver which let's say is used by windowsclients only,
if one just could have created a windows-link even more easily. It's the
total difference between both. With a unix-link, you don't have to
worry whether your application is able to follow windows-links the way you
expect it, it simply works, and you don't need to maintain additional
shares, it's accessrights etc - ok, but this is not the point [this indeed
could be extended to a debate on principles ;-) ]
The point is, that sometimes you just effectively need directories and
no links, but there is no way to copy stuff - as it is in our case:
the samba-server is a former nfs-server and the application running on
windows formerly used to run on IRIX and now was ported to windows using
hummingbird (btw.: the app. now beats the expensive SGIs in speed
immensively), which means that in fact it still is a unix-application
which has no idea of how to treat windows-links.
So: Is there not a way, to teach samba (maybe in a future-release) to
first check on recieving a deletion request whether or not a directory
possibly is a link and delete the link only? One could introduce an
per-share-option which allows to switch on this feature. I doubt this
could be that hard to realize, is it?
