Package: partman-base Version: 144 While testing a preseeded install that preserves a data partition (moving from lenny to squeeze), we discovered that the change from cylinder to optimal alignment makes the preserved filesystem unusable.
Create a partition scheme like this in Lenny: / = 10G swap = 1G /home = the rest Set up a preseed recipe that preserves the /home partition (see attached file for our example). We use simple-cdd to build custom installers that use our preseed install file. The partition alignment for all partitions is changed when the first two partitions are recreated and the /home partition is no longer mountable after install. I suppose it is very difficult to realign existing filesystems. Can the partition alignment be mixed with new partitions taking advantage of the potential performance benefits of the optimal setting, while preserving the existing partitions/file systems alignment?
