Okay - which program would do that?

Does it matter? If I remember correctly, libdevmapper creates the 
/dev/mapper/* nodes itself even if udev isn't there. So cryptsetup would 
create the temporary-cryptsetup-* node, access it and destroy it and 
udev would ignore everything else - sounds like a good solution to me.


I will deploy the rule mentioned in earlier posts as a workaroud for now 
and then see what is happening upstream - once the upstream rules are in 
a good state, I am more than willing to use those rather than 
distro-specific ones.
