Frozen mirror (with DebMirror and Scaramanga)

Frozen mirror (with DebMirror and Scaramanga)
	Part I. Miscellaneous subjects (and those still to be sorted)

Specify a script to run

We want to run a script instead of the default rsync command, so we specify which script to run in /etc/scaramanga/dists.d/ubuntu-frozen-testing:

	    SCRIPT=ubuntu-frozen-testing

Create the script

That script is looked for relative to /etc/scaramanga/scripts.d, so we put in /etc/scaramanga/scripts.d/ubuntu-frozen-testing:

#! /bin/bash

CONFFILE=/etc/scaramanga/scaramanga.conf
[ -f ${CONFFILE} ] && . ${CONFFILE}

DST=ubuntu-frozen-testing

BASEDIR=${DESTPARENT}/${DST}

export GNUPGHOME=/var/lib/scaramanga/frozenmirror-keys/.gnupg

# From the debmirror docs:
#default rsync options are "-aIL --partial"

debmirror --verbose --source --host=localhost --method=rsync --root=:Ubuntu --dist=lucid,lucid-updates,lucid-backports --section=main,restricted,universe,multiverse  --arch=amd64 --diff=use --rsync-options="-aIL --partial --no-motd" ${BASEDIR}

(As you can see, this is a lucid-only, amd64-only frozen mirror)

Create the verification keyring

Copy /usr/share/keyrings/* from the package ubuntu-keyring to /var/lib/scaramanga/ubuntu-keyrings, and in /var/lib/scaramanga/frozenmirror-keys/.gnupg/, do: sudo ln -s ../../ubuntu-keyrings/ubuntu-archive-keyring.gpg trustedkeys.gpg

Creating/updating the mirror

Now we start the script with

admin@server:~$ sudo -u scaramanga scaramanga -d ubuntu-frozen-testing

(The same command is used to update the mirror when we temporarily thaw the mirror.)
