Package: linux-image-2.6.18-6-686 Version: 2.6.18.dfsg.1-22etch3 Severity: normal
We have applied several DSAs, for example, DSA 1653-1, and find that they replace the currently running kernel and don't keep a backup copy - the only possible "on-box" rollback would be to a much older kernel. We don't understand how this fits with Stable's conservative, logical update process (which we really like, btw). Is this really meant to happen or do we have something wrong? We've waited to file this bug because we thought we had something wrong and it hasn't caused a problem (yet) on Etch. We believe this has been happening since Sarge or earlier. We started using Debian on Potato. We have had a problem on Lenny where we needed to copy a kernel from another system using a rescue cdrom. Our googling finds several people making similar comments on lists, forums etc but nothing definitive. Below is an extract from the aptitude log, showing the last few kernel upgrades. The Debian package version is changing, the kernel version shown by $( uname -r ) isn't changing.
