Since performance principle number 2 listed at 
http://gnuarch.org/arch-tech.html is: "Disk space is cheap", one would 
get the impression that Arch also is not shy about using lots of disk. 
:-)  Since I haven't actually used Arch, I don't know how this pans out 
during real day-to-day use.

So far the chandler CVS module is around 11MB, so in the grand scheme 
of things disk-space usage will probably rank low on the list of 
deciding issues.  It's good to have all the pros and cons spelled out 
though.  Actually, I just found this document from someone who has 
spent some time looking at Subversion, Arch, and Monotone (somewhat):
