The next Skolelinux release will soon be released. This will finally be based on Debian Sarge. For me one of the major advancements is the language support. The installation and most of the system can be used in Spanish. This was not the case with Skolelinux 1.
In the past weeks we have translated the default Apache homepage (for the server installation) and the LDAP user admin in Webmin. Also parts of the installation suddenly were in English again, but with help of the mailing list we fixed that as well.
So it seems to me that we have a nice Spanish Skolelinux system. A few parts are not translated yet, such as the Netgroup administration. I hope to address that in future Skolelinux upgrades.
And here at the Diego Thomson we already use the Sarge-based system. We installed it from the release candidates and it works just fine.
