Surely sushi deserves its own syspkg, so that (in some future where
syspkgs are useful), those who don't want sushi can easily exlude it,
and those who do want it can easily keep it up to date?

At present, sushi is the largest part of the base-sysutil-* group of
syspkgs.

$ grep base-sysutil distrib/sets/lists/base/mi | grep sushi | wc
     288     577   17718
$ grep base-sysutil distrib/sets/lists/base/mi | grep -v sushi | wc
     134     268    5010
