Bug Description

Binary package hint: partman-auto-loop

Disk images need to be contiguous (as much as possible) with disk space pre-allocated. The only way to do that in linux I am aware of, is to use dd if=/dev/zero, but that is slow for large images. Apparently though, using the default bs=4k, things get quite speedier (thanks to Szabolcs Szakacsits for the tip).

There has been no reply to the previous question, therefore it is being closed. In future please use ubuntu-bug to report any bugs you may find.
Note: Maverick uses bs="1000000", which is bigger than the report intended.
