The "do*" family as documented in the Developer Handbook[1], are defined
as "Installs the specified files/libraries...", and make no mention of
"Installing any...", granted we may be into semantics here.

Someone brought up missing README, COPYING and other documents as an
example of where "do*" should not be required to die. Someone else
brought up the example of a missing file such an initscript, in which
case "do*" should definitely die. On the question of eclasses containing
dodoc's that are 'allowed' to fail, the gnome2 eclass allows derived
ebuilds to set DOCS="foo bar", and will dodoc to all these files. So
each ebuild can specify the docs that are available, and dodoc is never
relied upon to fail. 

We shouldn't be relying on the existence of a file at package time if
we're specifically installing it.
