new bin builder setup

packages and chroot
~~~~~~~~~~~~~~~~~~~
1. install pld-builder from th repoeistory on target host

2. create chroot /srv/chroot
(you can symlink to real dest for the sake of copy-paste from here)
mkdir -p /srv/chroot

- if you're using rpm < 4.5-29, make system rpmdb linked to target rpmdb, as
  rpm gets it all very messy. see LP#395177.
mv /var/lib/rpm{,-host}
ln -s /srv/chroot/var/lib/rpm /var/lib/rpm
install -d /srv/chroot/var/lib/rpm
rpm -r /srv/chroot --initdb

therwise it's just:
rpm -r /srv/chroot --initdb

- install distro gpg key as default th config packages are signed and sign verify enabled in config:
rpm -r /srv/chroot --import /etc/pki/rpm-gpg/PLD-*.asc

- setup minimal /dev
install -d /srv/chroot/dev
cp -a /dev/{full,null,random,urandom,zero} /srv/chroot/dev

- install vserver-packages, but as it is usually hidden, so you must unhide it
  with --noignore:
poldek -r /srv/chroot -u vserver-packages -Q --noignore

- install pld-builder-chroot from th repos
poldek -r /srv/chroot -u pld-builder-chroot -Q --sn th --sn th-ready

- make rpmdb readable for builder user
chmod -R a+rX /srv/chroot/var/lib/rpm

- setup /srv/chroot/etc/resolv.conf so if you enter manually you can work with poldek
cat /etc/resolv.conf > /srv/chroot/etc/resolv.conf

- restore rpmdb hack
rm -f /var/lib/rpm
mv /var/lib/rpm{-host,}

gpg keys
~~~~~~~~
1. import src builder key to bin builder so it can download queue.gz

src-builder$ gpg --export builder-th-src@pld-linux.org --armor > th-src.asc
bin-builder$ gpg --import < th-src.asc

2. generate new key for bin builder and import it to src builder so it can
   accept spool/notify messages

3. import that public key to src builder keyring
bin-builder$ gpg --gen-key
bin-builder$ gpg --export KEYID --armor > th-i686.asc
src-builder$ gpg --import < th-i686.asc
 
ssh keys
~~~~~~~~

generate key on bin builder and add it to authorized_keys of ftp account

i.e account where you push your uploads:
[th-i686]
ftp_url = scp://fpldth@ep09.pld-linux.org:ftp/.tree/.incoming/i686/

bin-builder$ ssh-keygen
bin-builder$ ssh-copy-id -i .ssh/id_rsa.pub fpldth@ep09.pld-linux.org

buildlogs
~~~~~~~~~
buildlogs are copied with rsync. ask buildlogs.pld-linux.org admin to allow your ip
also you need to setup password that is used to authenticate in rsync-passwords

sudo access
~~~~~~~~~~~
make sure builder user (who runs crons) can sudo chroot to the chroots:
builder ALL=(ALL) NOPASSWD: /usr/sbin/chroot /home/users/builder/chroot-th *

testing
~~~~~~~

keep /var/lib/pld-builder/spool/log running with tail -f
run the cronjobs under builder account.
