Whiteboard

Discussion Points:
 * (At least) the 3rd UDS where this has been discussed... What are the blockers?
  * time/resource to do it?
  * hibernation/resume?
 * Originally, I was thinking about offering swap files as an option, in addition to swap partitions; does this make sense? Would it be better to just default to swap files now, and allow for swap partitions in manual partitioning schemes?
 * What about GUI/command-line utilities for management of swap files?
  * a slider to dynamically adjust the size
  * a checkbox for encryption (see encrypted swap spec)
 * Server vs. Desktop installer -- should this be handled any different between the two? (I think not)

One common item is a multiboot setup. If this were implemented, and it would do a mkswap for official swapfiles when activating them, I could share large, contiguous files (e.g. windows PAGEFILE.SYS) among the systems instead of having several large files, one for each OS.

If in the installer, there is a partition going to be mounted, allow the user to select a file. As a post-install, add a swapfile manager where files can be selected, created, or removed.

scott - I'm not touching the installer ;)
