its absolutly not true at all, woody's base is larger then potato's

using debootstrap to create a clean woody base, then removing the
.debs from var/cache/apt as well as the fake lists from var/lib/apt
and tgzing the result i have:

-rw-r--r--    1 root     root     22005075 Nov  1 14:57 woodybase.tgz

potato's base2_2.tgz:

-rw-r--r--   1 debian   debian   16538806 Apr 15  2001 base2_2.tgz

additionally, due to the way debootstrap works, if your using a single
root partition layout your root partition must be no less then 100MB
for a sucessful install, this is because you must have room for both
the unpackaged base system AND all the .deb files it comprises.  the
.debs cannot be removed until after the base system has been completly
extracted and isntalled.  this affects CDROM installs as well since
debootstrap copies all the base .debs into var/cache/apt/archives.

the extracted base plus the .deb files is 92MB, but i think you likly
need a few more since dpkg is used to reinstall most of the base
packages at the end to sanitize the dpkg databases, 100MB has shown to
be sufficient in most tests.  (you can of course have a smaller /
partition if you split off /usr and /var).

so its safe to say you need double the ammount of space you needed for
potato base installs.  

some stats (generated with du -sh):

65M     woody
56M     potato
50M     woody/usr
44M     potato/usr
3.6M    woody/var
2.2M    potato/var
eb@ash ~/tmp$ chmod 0 woody/usr woody/var potato/usr potato/var
12M     woody
9.9M    potato

with the base .debs not removed:

91M     woody
30M     woody/var
22M     woody/var/cache/apt
4.7M    woody/var/lib/apt/lists

this is all on the powerpc arch, but there are no new packages added
to powerpc's base that were not added to all architectures, the space
requirements will be slightly less for i386, but still porportional.
(since powerpc binaries are slightly larger then i386 binaries).
