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.
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:
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.
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
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...
This works for me.
