First: For such questions you should probably first ask @sernet
first, unless you are certain it is a pure samba issue.
But as this might hit several people:

The new version uploaded later yesterday offers to configure
a dns forwarde in the "dcpromo" dialogue. This should leave
your dns setup much more useful without the need to change
resolv.conf. (This feature was not available in upstream samba
for the first version of the appliance. Now it is... :-)

The reason you can't modify the resolv.conf is that the dcpromo
makes it immutable with "chattr +i", in order to prevent it from
being overwritten (by e.g. dhcp). If you need to change it, you
can use "chattr -i" to remove the immutable attribute.
