Ah, right. Sorry about that.

A few more notes:

- the build system also embeds information about the build host, at
  least the kernel version and hostname. Those need to be stripped too.
  From 'perl -V':

    osname=linux, osvers=3.16.0-4-amd64, archname=x86_64-linux-gnu-thread-multi
    uname='linux estella 3.16.0-4-amd64 #1 smp debian 3.16.7-ckt2-1 
(2014-12-08) x86_64 gnulinux '

  I assume varying uname et al. isn't actively tested yet?

- I would expect some of the generated manual pages to embed the build
  date, at least for patched modules like Net::SMTP. Are builds from
  different days compared currently and/or are you setting POD_MAN_DATE
  externally? (see #759405)

- I don't think 0003-Allow-cf_time-to-be-set-externally is needed,
  as config.over can override cf_time without it AFAICS.

Sorry I'm a bit slow with this... :)
