My Kerberos server runs 7-STABLE and has a 93M root with 25M free.  It's a bit 
tight -- I have to remember to disable the installation of debugging symbols 
for the kernel and modules, for example.  However, it does work fine, and 
that's even with modules installed.  The bigger problem is my old /var now 
that I have audit enabled.
