Bug Description

Looking at syslog I can see that it seems to install all the langpack and then remove the unusefull.
It waste a lot of time doing this

Yes, it does spend a considerable amount of time removing langpacks.

Ubiquity is clever enough not to copy files from the langpacks that won't be used post-install, unfortunately all the fonts and some other packages still need to be cleared and their postrm called. This can take up to 50% of an Edubuntu install but won't be fixable unless we do very ugly tricks in ubiquity or do a major rework of all the langpacks and font packages to reduce their install/removal time.

Anyway, even though I don't think we have a bug on LP yet, it's been a known issue of Edubuntu ever since we moved back to the DVD format. This issue also affects any other DVD image containing a significant number of langpacks.

Another alternative we considered was simply not to cleanup the langpacks, keeping them all installed, but we thought that was a very bad idea as it'd make for huge upgrades when the langpacks are refreshed, wasting much more than the extra 20min or so of install time, just in downloading these updates and installing them.
