Remastering Tinycore.gz HowTo - A simple way

(1/3) > >>

Pats:
This is the procedure for extracting and repacking of tinycore.gz file. I think same may apply to core.gz.

Extracting tinycore.gz :
----------------------
mkdir /tmp/temp
Copy tinycore.gz to /tmp , then
cd /tmp/temp
zcat /tmp/tinycore.gz | sudo cpio -i -H newc -d >/dev/null

Remaster/make changes to the extracted tinycore.gz which must be now somewhere under /tmp.
re-packing tinycore.gz from remastered version:

Delete /tmp/tinycore.gz , then
cd /tmp/temp
sudo sh -c "find . | cpio -o -H newc | gzip -2" > /tmp/tinycore.gz

Note: Use sudo where-ever required. Also there is good explanation in Remastring section of Wiki and the Forum's posts.
Posted on the request of a newbee. Hope this helps to others also.

Why -2 used with gzip?

Some optimization:


--- Code: ---zcat /tmp/tinycore.gz | sudo cpio -i -H newc -d >/dev/null
--- End code ---

can be replaced with


--- Code: ---zcat ../tinycore.gz | sudo cpio -i -d
--- End code ---

to make it shorter and portable.

For packing


--- Code: ---sudo sh -c "find . | cpio -o -H newc | gzip -2" > /tmp/tinycore.gz
--- End code ---

can be shorten to


--- Code: ---find | cpio -o -H newc | gzip -9 > ../tinycore.gz
--- End code ---

As described in the wiki but  advdef -z4 tinycore.gz  is mentioned in the wiki, too.

I'm wondering, could we remaster core.gz using any compression level or do certain requirements need to be met? I have slow network connections and CD drives in mind. I recently booted tinycore on an ancient 233MHz laptop via CD which took quite some time after choosing a menu entry from the boot loader. I guess it was either decompressing the initrd or reading it from the CD which took so long.
