Package: netcfg
Version: 1.197
I have (re-)created a Debian netinst boot-stick incorporating a tailored
preseed.cfg.
For some reason I need server names with a node-name only (like "timeserv").
Without a dns-domain, so not a FQDN.
This wouldn't be a problem if /etc/resolv.conf contains a line
"search <dns-domain>"
Unfortunately netcfg fails to write it.
I have modified postinst to do this. See patch.
Maybe it would be better to modify the netcfg itself. But this is beyond my
scope.
