Package: debian-installer
Version: 20130430
Severity: wishlist

I tried installing Debian 7.0 on a system with a fairly slow disk (an Asus
eeepc 901), so I enabled btrfs and compression, which made the install
process go very slowly. Doing so, I noticed that the man-db triggers are
called very many times during installation (after almost every second
package when installing the base system, and fairly often during the regular
install). On my configuration, each invocation took a few seconds, causing a
noticable delay (full install took about 14 hours).

If man-db was installed last, its trigger would only need to be called once,
which would be an enormous performance win.

Because of this, I hereby close this bug report as there is nothing we
can really do here. D-I shouldn't indeed have to worry about package
installation order optimization, that's the job of the lower-end
tools.

But I guess that, anyway, the swtich to "nowait" will considerably
reduce the impact of man-db on the system.
