The set of packages currently on AUR is *huge*, I think Don recently
mentioned
something in the order of 2000 haskell packages on AUR, and that is
about 10%
of AUR.  I would suggest starting somewhat smaller than that :-)

Maybe starting from Haskell Platform and growing on demand from that?

The size of the .git dir is:

  % du -sh .git
  30M     .git

For comparison I changed strategy for darcs, instead I recorded each package
in its own changeset:

 Total time to add and record: 7638.14s user 1108.26s system 99% cpu
2:26:04.82 total
 Size of the whole work area: 436M
 Size of _darcs: 409M
