Bug#1006829: freeipa-client missing dependency on libnss-myhostname

[Michael Stone]

Please do not add this unnecessary dependency. If the /etc/hosts file is 
properly set up the enrollment will work fine without it. If someone 
wants to use libnss-myhostname instead of properly configuring 
/etc/hosts it's available as an option, but don't make everyone install 
it for no reason.
