:I made a new Hammer filesystem on the laptop disk and looked at the output of
:hammer cleanup, which shows no dedup. I ran hammer config on it, and there is
:a dedup line, but it's commented out. The PFSs have no config. How come?

dedup isn't turned on my default. dedup is being used regularly now
but deduplication in general can lead to I/O fragmentation so it isn't
the default. Not everyone needs dedup.
hammer cleanup should have installed a default config for each PFS.
