That could be quite messy, esp=2E from the point of view of port=20
specific kernel options (like CPU type) at the configuration side, plus=20
disc space overheads of having several cross-compilers/linkers=2E

nice 18 springs to mind=2E  This would obviously slow down the=20
compiles, but would make the running of the system almost transparent=2E

     heh, a good idea=2E=2E=2E=20

I think it would be quite tricky to do a direct comparision of two=20
compiles, and keeping loads on disk would also take a lot of space, but=20
keeping some from say, the last seven days along with their configuration=20
details would be handy=2E  Also, regular builds of extremely common=20
("standard") configurations from -current?=20
    =20
     well how many possible options are there in a config?  after the user=20
     fills out the online form (or emails the config file to the server)=20
     the generated config file is passed thru some instrument that sorts=20
     its out and makes sure that two config files that have the same=20
     options look the same=2E  then it would pull up the cache of the last=20
     hundred or so (say 1 or 2 megs per kernel and it really isnt that=20
     much) and search for the exact match of the config file=2E  then just=20
     serve it up or copy out the src/sys tree to a new home and build=20
     away=2E=2E=2E
    =20
     maybe users could even email their kernel orders=2E=2E=2E
    =20
     if this ever gets done it would make for a cute little 'first' that is=
=20
     of course if it is a first of its kind=2E=2E=2E
