I agree: it probably explains the difference between Gentoo's package manager
and and tl's network installer (this, and as Martin mentionned, the fact that tl
installs some 5000 packages). But I'm affraid we can't use this solution, for
the following reason.

This is necessary if you want to be able to distribute a tlpdb which is probably
older that what some mirrors have. Otherwise the tlpdb listing of the files for
a given package might not match the files that are actually in the archive, and
this may cause a lot of problems.

I'm afraid there are problems, too, but I think it is really worth thinking
about it, since issues with the network installer are quite frequent.

I agree with both of you :-)
