no debian package is a showstopper for us.
Also some of our users will scale quite large so "slow" is not good
altho i do not know if you mean slow in resolving queries. or slow in
propagating changes... so "slow" may or may not apply.

no we do not use updates from dhcp.
we give machines names by registering them in dns. and machines learn
this when they boot.
That is why registering dns names and mac addresses in ldap is very
important for us. they are fundamental for a functioning network. and
gosa hopefully will make this easier.

personally i do not think we want to change such a fundamentalt
architecture design at this time in the release cycle. or if we even
want to change it at all..

we are thinking of them more like machine objects that should contain
all information needed by the machine. (hence dns and dhcp) while i
agree that it does give us headache atm.
