To me, that seems excessively complicated. But each to his own.

When I measure for the book, I don't usually make logs! If I am
making logs, I usually put them in ../ and use du for the directory
and for the DESTDIR or equivalent directory.

Agree, I see large variations - even in remeasuring the SBU.

Did I write that ? I intended to say that rebuilding the API docs
took a lot of extra time, but that the space used was 1MB less - I
guess that the recreated docs are trimmed down.

It is clear that my rebuild of the docs was very different from
Fernando's. At the moment I'm concentrating on rebuilding
everything in chroot, just in case there is any breakage from
accidental change in gnutls. My first attempt at LO just timed out
on one of the downloads, so I guess I'm hours away from completing.
After that, I'll take another look.
Unfortunately, this system with gnome packages is my only 7.5
system with gtk-doc and p11-kit, so I can't do comparative tests on
the other box.
What I did notice was a *lot* of activity during the rebuilding of
the docs (not logged, so I watched stdout scroll past, with
references to html at one point.
Guess I'd better create logs when I come back to this, so that I
can summarise the difference in the builds.
