Hello Forum,
a last year before christmas I started to installe my gentoo XEN server with the dom0 based upon hardened sources. I used the (at that time) latest stage 3 tarball downloaded from the Technical University of Vienna at http://gd.tuwien.ac.at/opsys/linux/gentoo/releases/amd64/autobuilds/20131219/hardened/. This (historic) tarball is stil available as http://gd.tuwien.ac.at/opsys/linux/gentoo/releases/amd64/autobuilds/20131219/hardened/stage3-amd64-hardened-20131219.tar.bz2 and has a compressed size of 169.397.367 bytes.

After a few issues with a brand new harddisk that developed read erros and therefore required an RMA it took some time before I was able to start my first domU installation a few days ago. Following the recommendations in the installation handbook (and also because the old tarball was no longer available) I again downloaded the (at that time) latest stage 3 tarball from the same source which, again, is still available at http://gd.tuwien.ac.at/opsys/linux/gentoo/releases/amd64/autobuilds/20140123/hardened/ as http://gd.tuwien.ac.at/opsys/linux/gentoo/releases/amd64/autobuilds/20140123/hardened/stage3-amd64-hardened-20140123.tar.bz2. This file however is much larger at 181.103.064 - a (compressed) size increase of 11.705.697 bytes.

This only came to my attention when it appeared that the new domU system, disounting the packages I explicitly had installed in my dom0, had many more packages than my old dom0 system - which in a way seemed strange.

Further investigation seemed to confirm that gentoo in their stage 3 tarball have made a switch from the standard man package (linux manuals) to the man-db package which, most likely due to dependencies, pulled in a number of further packages like
Code:
openjade
po4a
opensp
numerous packages from the perl-core series
numerous packages from the the dev-perl series
all of which do not show up on the old dom0 system.

Could anybody shed some light on whether this is the cause of the size increase and the subsequent increase in the number of installed packages? I could not find any information about that change anywhere, but may have looked in the wrong place ...

What is the advantage/disadvantage between the two man packages and would it make sense to update the old installation to the new package or rather downgrade the new installation to the old man pages? I'd like to keep my systems in sync as much as possible, but also as slim as possible without unnecessary bloat.

Thanks in advance,

man-db is definitely worth using - not for the man command itself, but for the much
improved apropos and whatis programs. However, I don't know why it's suddenly
starting pulling in endless perl stuff, which I noticed in my last build and never
investigated. There's nothing in the portage changelog.

Will,
thanks for the info on the man-db. So in order to keep my systems synchronized, I'll update the dom0 to man-db as well - despite the perl crap that seems to be pulled in.

I'd at least have expected some information about those changes, but as you rightly said, I also couldn't find anything in the changelog.

Another unexpected thing that struck me and obviously also somebody else (see here) seems to be that udev is no longer automatically added to the proper run-level during the installation process. Sometimes strange things can happen ...
