howto run jigdo as admin

for Nextime Jaromil or Daniel, or whoever runs the beta download server

I made .jigdo files but I don't have access to your servers (nor do I need to) so here's how I made them:

First install jigdo-file

# apt-get install jigdo-file

the program needs read-only access to the ISO image, and a scratch directory with more than 4.7Gb room to work in.

# mkdir scratch
# cd scratch

copy the image to the scratch directory (probably not necessary)

# cp somewhere/devuan_jessie_1.0.0-beta_amd64_CD.iso .

mount or loop-mount the .iso image readonly

# mkdir Devuan
# mount -v -o ro,loop -t iso9660 devuan_jessie_1.0.0-beta_amd64_CD.iso Devuan/

collect the list of files inside the ISO image

# find Devuan/ -type f -name '*.deb' -o -name '*.udeb' |sort > FILES.tmp

N.B. take care that everything on the DVD is the same as in the pool/; when I tested my .jigdo it complained about apt-setup-mirror misssing or something.

edit FILES so that it contains // to indicate what the label bit of the directory path is:

# cat FILES.tmp | sed -e 's?^Devuan/?Devuan//?' > FILES

Then run jigdo-file, it goes surprisingly quickly:


# IMAGENAME=devuan_jessie_1.0.0-beta_amd64_CD
# URI=http://packages.devuan.org/merged/

N.B. it is important that the URI has a trailing slash


# INPIMAGE=$IMAGENAME.iso
# JIGDO=$IMAGENAME.jigdo
# TEMPLATE=$IMAGENAME.template
# FILES=FILES

# if [ ! -f $FILES ]; then
#   echo "generate $FILES first"
#   exit 0
# fi

# jigdo-file make-template --image=$INPIMAGE --jigdo=$JIGDO --template=$TEMPLATE --files-from=$FILES --cache=jigdo-cache.db --label Devuan=Devuan/ --uri Devuan=$URI


Then remember to umount the .iso image

# umount Devuan

Expect the .template file to be around 30 Mb (CD or DVD doesn't matter).

You may want to edit the .jigdo file before uploading, especially the [Servers]
header.

[Servers]
Devuan=http://packages.devuan.org/merged


Your downloaders will not use the jigdo-file program, but the jigdo-lite program instead.
