Compression

[Ty9000]

Is there any way to set compression levels in Fog 0.32?

Thanks!

[Tom Elliott]

Yes, but not real easily.

The way to do it is described below: (root access on FOG Server, use terminal or console.)
[code]cd /tftpboot/fog/images
mkdir tmp
gunzip -d -c init.gz > init
mount -o loop init tmp
sed -i ‘s/PIGZ_COMP=“-3”;/PIGZ_COMP=“-0”;/’ tmp/bin/fog #THE -0 change to what you want. -0 is worst compression, -9 is best compression.
umount tmp
mv init.gz init.gz.orig
gzip -9 init
rm -rf tmp[/code]

Thank you, thank you, thank you! I just manually modified the file once it was unzipped. Running the code the first time screwed it up (probably my fault!), so I just modified the file.

That’s so awesome! Thanks again!!!

Glad I could be of assistance.

Hi Tom, so on another install I did follow the guide above; now the begining of the file looks like this:

[CODE]#!/bin/sh

PIGZ_COMP=“-9”;
RUN_CHKDSK=“”;
HOSTNAME_EARLY=“0”;
[/CODE]

However during an upload the blue screen still says Compression level… None

Is there another place to enable compression per-se which is an independent setting from the level of compression?

Thx

this information pertains to fog 0.32
if you are using fog 1.0 (or fog 0.33b) the setting is changed on the configuration page under boot settings

Thx [SIZE=12px]Junkhacker; I’m on 0.32 in this case; after some testing I think the message “compression level…” may not be credible; if when it says NONE the imager clearly uses compression since the final *.img file is nowhere near the actual partition used up space. Could there be some truth to that?[/SIZE]
