Just a few days after the eighth update of etch (4.0r8), the Debian project announced the first update of lenny. Opposed to the etch updates, this receives a minor numbering in the version 5.0.1 and also updates the /etc/debian_version file with this information; even if this is a simple change, I like it a lot as it will make it much easier to identify what update level a machine is running (just like redhat world had forever in /etc/redhat-release ;-) ). Besides this cosmetic change, most of the updates were already on security.debian.org; still there is a kernel update (minor version update of course) that fixes some openvz, nfs bugs (see debian kernel changelog for full details) and because of this also an updated debian-installer.
“The Debian project is pleased to announce the first update of its stable distribution Debian GNU/Linux 5.0 (codename lenny). This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems.
Please note that this update does not constitute a new version of Debian GNU/Linux 5.0 but only updates some of the packages included. There is no need to throw away 5.0 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.
Those who frequently install updates from security.debian.org won’t have to update many packages and most updates from security.debian.org are included in this update.”
