This simlink should be a directory /dev/dvb/HP1250 containing simlinks
to all the device nodes in /dev/dvb/adapter6
Isn't this the simlink created by your earlier tries a few weeks ago?
If everything works: ls -l /dev/dvb/* should give you the two adapter
directories with contents and the newly created directories with
contents. Try replacing /bin/sh with /bin/bash in your rule!
