intro
BLAG is a moving target [this is a feature, not a bug...] At any one time there's usually a stable version [currently 90001 (oxygen)] and a development version [which is what BLAGHEAD may be considered to be, BLAGHEAD does not have an ISO]. It's good to have a copy of the current stable ISO on your hard disk somewhere [so that you can burn copies for your friends and also so that you can seed the ISO via Bittorrent].
FREEEEE has however a much quicker development cycle, at the time of writing at least. New installation images are produced almost daily and are in ext2 format. Note there is a download script: freeeee-download for the current image.
Downloading the full ISO/ext2 every time there's an update is wasteful of both your and BLAG's bandwidth. One way to download just changed parts of the ISO/ext2 is to use the wonderful program, rsync.
Here's a howto for rsync'ing a BLAG ISO or FREEEEE ext2.
method
BLAG ISO
The following should work when the next update to 90002 happens. It assumes you have a pre-existing BLAG ISO and the associated SHA1SUM file in the same directory.
Go to where your existing image is:
cd path/to/where/your/iso/lives
Rename it:
mv BLAG-90001.iso BLAG-90002.iso
Run the rsync commands for the ISO and the SHA1SUM file. Note trailing "." -- it indicates to write to the current directory, you could substitute it with a filename:
rsync -Pz --stats --progress rsync://rsync.blagblagblag.org/blag/90000/en/iso/BLAG-90002.iso . rsync -Pz --stats --progress rsync://rsync.blagblagblag.org/blag/90000/en/iso/SHA1SUM .
Check the SHA1SUM of the image against what it should be:
sha1sum BLAG-90002.iso ; tail -n 2 SHA1SUM
The two SHA1SUMs should be identical. If they aren't, it's jacked. Don't use the rsync image for installing BLAG.
FREEEEE ext2
Same process, just a different domain and file names. This example uses the latest two images at the time of writing [or last edit].
cd path/to/where/your/ext2/lives mv FREEEEE-200810131828.ext2 FREEEEE-200810150722.ext2 rsync -Pz --stats --progress rsync://rsync.freeeee.org/FREEEEE/images/FREEEEE-200810150722.ext2 . rsync -Pz --stats --progress rsync://rsync.freeeee.org/FREEEEE/images/SHA1SUM . sha1sum FREEEEE-200810150722.ext2 ; tail -n 2 SHA1SUM
scripts
Based on freeeee-download mentioned above, I am attempting [as my first attempt at such a thing] to write two scripts: blag-rsync and freeeee-rsync, stay tuned...
blag-rsync
in progress.
freeeee-rsync
in progress.
freeeee-download
This works for me.
#!/bin/bash # freeeee-download # to download the latest version of the FREEEEE ext2 installation image. # # sometime sep-2008 jeff <moe@blagblagblag.org> - 1.0 # original version wget -c http://freeeee.org/images/SHA1SUM IMG=$( tail -1 SHA1SUM | cut -f 3 -d " " ) wget -c http://freeeee.org/torrents/$IMG.torrent aria2c \ -s 2 -c \ --seed-ratio=0.1 --seed-time=1 \ -T $IMG.torrent \ http://www.freeeee.org/images/$IMG \ ftp://www.freeeee.org/FREEEEE/images/FREEEEE-$NOW \ http://www.blagblagblag.org/pub/FREEEEE/images/$IMG \ ftp://ftp.blagblagblag.org/pub/FREEEEE/images/$IMG
