But swap is a kernel entity; surely your argument could be extended to
the buffer cache aswell; since it's mostly (only?) user programs
writing to the disk thru the bufcache in the first place, shouldn't
syncing the cache with the disks before reboot/halt done by a user
process aswell? Yet the kernel does this automatically when unmounting
the filesystems (to my knowledge). IMHO it would be just a lot more
practical if the kernel would properly unconfigure swap devices itself,
especially when raidframe is being used.
