Hi,
(sorry for top-posting)
Unfortunately, reading is not the only operation with the data -
YaST also writes them quite extensively.
I don't really know what exactly the problem (internally) is,
anyway, I have one suggstion:
Does reading/writing of the AutoYaST profiles, installation
workflow definition and similar files work?
I tried the XML approach in the ntp-client, IMHO it looks better in
this case, you can compare
https://github.com/yast/yast-ntp-client/pull/6/files (XML solution)
https://github.com/yast/yast-ntp-client/pull/5/files (include file)
The advantage is that the data is XML file which can be read also by
tools outside yast and it is a true data file (in contrast to include
which is basically a piece of code).
Any opinions?
From my point of view it is fine as long as such file is automatic
generated. I really don't want to write such beast manually :) even
reading it is pain.
Question is what happen during installation as you read it now
directory and before agent is used, so does it read from same location
in both cases?
Well, when the code is migrated, the YCP data files will also be
migrated; that's a matter of a simple YCP script.
The more difficult part will be migration of data created on run-time...

P.S.: Here is the script which I used for creating the XML file:
{
// read "servers" content
include "ntp-client/ntp_servers.ycp";
import "XML";
map doc = $[];
doc["cdataSections"] = [];
doc["listEntries"] =$["ntp_servers":"ntp_server"];
doc["rootElement"] = "ntp_database";
doc["systemID"] = "/usr/share/YaST2/control/control.dtd";
doc["nameSpace"] = "http://www.suse.com/1.0/yast2ns";;
doc["typeNamespace"] = "http://www.suse.com/1.0/configns";;
XML::xmlCreateDoc(`ntp, doc);
XML::YCPToXMLFile(`ntp, $[ "ntp_servers" : servers], "/tmp/ntp.xml");
}
Then you can read the content by
{
import "XML";
y2internal("NTP: %1", XML::XMLToYCPFile("/tmp/ntp.xml"));
}
(BTW I had to manually fix the YCP data as there were some
XML entities which made troubles when parsing back the saved XML
file.)
