I see. There is no such automation in poldek (yet maybe), hold= prevents
packages to be upgraded only, held packages are just skipped during 
--upgrade-dist.

Newer than installed packages are displayed by "llu" and "llU" 
interactive commands (aliases for "ls" in fact, see "ls --help". 
Interactive commands may be accessed in 3 ways:

poldek> llu kernel* 

or 

$ poldek --cmd llu kernel\*

or 

$ ipoldek llu kernel\*

Command line -i switch: 

$ poldek -i kernel 

or by interactive mode command "install" with -I and -N switches.
"just-install" mentioned above is an alias for "install -IN", 
see "install --help".
