Also, bare exceptions are bad!

+    except:
+        service.print_msg("Could not determine entropy, possible long delays")

Next, you do all the checks in ipa-server-install, while they should be in
service files, like krbinstance.py so that it is also checked in other
installers, like ipa-replica-install.

Same for DNS, it should be a separate step in bindinstance.py so that when the
installation is hanging, you can see

 [X/Y] Generating rndc key file

and know that it is hanging on that part.

I would not misuse "service.print_msg" for regular messages, I would only do the

service.print_msg("WARNING: Your system is running out of entropy, expect long

others can be either turn into separate installation step or debug log message.
