XZ compression command line - init.xz
I’m trying to modify the Init Image on a new 1.0.0 installation, and trying to accomodate for the new XZ compression method. I managed to use the following command line to extract it successfully:
[CODE]xz --decompress init.xz[/CODE]
and the following command line seems to successfully re-compress it:
[CODE]xz --compress init[/CODE]
however when i try to PXE boot, i get an error that the XZ compression method used is not supported. can you tell me the correct way to extract/compress the new init.xz image in the 1.0.0 distribution?
here is my entire init-modifying script:
xz --decompress init.xz
mount -o loop init initmountdir
xz --compress init
chown fog:www-data init.xz
echo “repacked, ready for client deployment”[/CODE]

That is correct.
Sorry I didn’t get a chance to be of assistance, and I will have to create a WIKI to add these minor changes.
XZ requires a small portion of encryption.
…i think i figured it out! after some googling, i added the CRC32 check and it seems to work normally. here is my whole command line:
[CODE]xz -z -9 -C crc32 init[/CODE]
hope this helps others!
…specific message im getting during PXE boot is:
[CODE]Input was encoded with settings that are not supported by this XZ encoder[/CODE]
thanks in advance!
