Subject: filesystem does not allow ln to create bad symbolic link

<not a bug, asking for advice>

I have a non root ssh account on a shared host; was unable to get the distro name.
I'm trying to untar several tar archives. Some of the sym links are bad until
all of the archives are untarred.

It's a large unknown filesystem - see df output.

The problem - ln refuses to create a bad symbolic link!

Has anyone run into this before?  My install script depends on
untarring a few bad sym links, which get resolved by later untars in
that script.  This script has worked fine for me on a dozen or so
centos, fedora, or umbuntu hosts for years.

Any comments appreciated.  Appears I have to rewrite the bash install script to untar all the
sym link target files first.  I plan to ask the host provider for help, but any
tips would be appreciated.
