hd-media/boot.img.gz resize

[blockbuster5]

Hi,

Is there a way I can resize or get a bigger boot.img.gz of debian? I would like to put in a bigger image than the current 1G limitation.

Thanks!

I guess you can uncompress the image, extend it, extend the partition and filesystem inside, and compress the image again.
May I ask why you want to use this image ?

Once the image is uncompressed, how can I extend it (extend the partition)? Any commands or tools?

I looked online and tried: sudo qemu-img resize boot.img 3G
But when I write it to a drive zcat boot.img.gz > /dev/sdb The filesystem is still 1G. How can I extend it?

I am going to add my own stuff to the image which will make it larger than 1G.

thanks!

You must resize the partition with any partition tool (fdisk, parted...) and the filesystem with that filesystem-specific resize tool (resize2fs for ext*, fatresize for FAT...). Thinking of it, I seem to remember observing that fatresize mangled the filesystem boot sector, so the image may not boot properly.

You know that the installation manual describes other methods to use a bigger image, don't you ?
