I'm not sure if you meant this to go to the whole list, but nothing bad was there so oh well ;)
I'll respond to the whole list as well:
DriveSetup is on my list of things to look into. You make a good point in that we can use the existing SoftwareValet and PackageBuilder for a while.
Are there documents anywhere regarding DriveSetup and how it would interact with the new file system architecture? Is all the ground work done at the low-level? Also what would be the best way to test, using spare hard-drives (I do have some) or would it be possible to test on "virtual drives" that exist on a partition? Maybe some of the techniques used to test the Haiku BFS implementation could be useful here.
Up front - i'm sorry I have not been helpful at all with the icon editor yet. To be perfectly honest, much more important than SV (i think) would be DriveSetup. The one from R5 cannot be used, since we have a new API for this stuff. Software Vallet OTOH and PackageBuilder are there and probably work. I know we cannot ship them with Haiku, i just mean DriveSetup is more urgent. That being, said, i have suggested to a couple people now that DriveSetup is a neat project.... though i don't know if anybody really picked up the idea. :-)
