Apt-cacher-ng : a cache server for... Pacman (and APT)

Question

Hello !
I just adopt apt-cacher-ng on AUR, because I'm using it for APT (I use debootstrap and chrooted environments) and it help me saving a lot of bandwith (531Mb today).
So here is the package if you are insterested :
http://aur.archlinux.org/packages.php?ID=40662
I've seen in the main configuration file that it can be used for Archlinux. So I did it
I will share my configuration in this topic.
Configuration
The main file is /etc/apt-cacher-ng/acng.conf
I'm using apt-cacher-ng only on my laptop :
BindAddress: localhost
Here are some Remap lines for Debian repositories (including security) :
Remap-debrep: file:deb_mirror*.gz /debian ; file:backends_debian
Remap-debsec: /security ; http://ftp.fr.debian.org/debian-security
This is the line for Archlinux
Remap-alxrep: file:archlx_mirrors /archlinux ; file:backend_archlx # incomplete, please create this file or specify preferred mirrors here
Here is a very permissive addition to the VfilePattern regex to allow the *db files (needed for pacman -Sy)
VfilePattern = (^|.*?/)(Index|Packages\.bz2|Packages\.gz|Packages|Release|Release\.gpg|Sources\.bz2|Sources\.gz|Sources|release|index\.db-.*\.gz|Contents-[^/]*\.gz|pkglist[^/]*\.bz2|rclist[^/]*\.bz2|/meta-release[^/]*|Translation[^/]*\.bz2|.*\.db)$
Just put in the file /etc/apt-cacher-ng/backend_archlx your nearest mirror without the "$repo/os/$arch" part :
In my case :
echo http://mir.archlinux.fr/ > /etc/apt-cacher-ng/backend_archlx
Usage
You can now restart apt-cacher-ng
rc.d restart apt-cacher-ng
Here is your new /etc/pacman.d/mirrorlist !
Server = http://localhost:3142/archlinux/$repo/os/$arch
Just in case, here is a minimal /etc/apt/sources.list for Debian :
deb http://localhost:3142/debian squeeze main contrib
deb http://localhost:3142/security squeeze/updates main contrib
Reflector
If you want to use the very last synced archlinux repositories, with reflector, you can do something like that
rc.d stop apt-cacher-ng
reflector -p http -l 1 --sort rate | grep -o -e 'http://[^\$]*' > /etc/apt-cacher-ng/backend_archlx
rc.d start apt-cacher-ng

Hi, thx for info. Just checking with  file:archlx_mirrors
that file needs to be created as well? Can I leave it
out and just have -> Remap-alxrep: /archlinux ; file:backend_archlx
I suppose I can just test it. I read the docs, but they are a bit confusing :-)
I'm not sure and I'm not a master of apt-cacher-ng Precise documentation is here :
http://www.unix-ag.uni-kl.de/~bloch/acn … tml#repmap
The file archlx_mirrors is in the package, and contains a list of mirrors.
The second part of Remap- line, TargetURLs, is optional.
Just try and give your results here please
