Archiso resize image

Following instructions on the Archiso wiki I successfully created a 'base' installation Arch Linux iso.
So far so good.

I copied the image with

dd if=archlinux-2016.03.27-x86_64.iso of=/dev/sdf;sync

onto a 32gB sdcard.

Booting the image works fine, however when I reviewed the partitions it showed:

sdb                   31.3G disk /run/archiso/bootmnt
|-sdb1              265M part
`-sdb2              31G    part
loop0              240.5M loop /run/archiso/sfs/airootfs    

The sdb2 part is not used, the complete filesystem is located in sdb1.

I would like to have Archiso use the whole disk.

After some research I found a forum post about resizing existing partitions, while mounted. They suggested to use

resize2fs

I tried to use

resize2fs /dev/sdb1

, however it ran into errors:

Device or resouce busy while trying to open /dev/sdb1

and

Couldn't find a valid filesystem superblock

.

What is the best way to have the Archiso to use all available diskspace?

Re: Archiso resize image

As far as I know, Archiso only creates live media. So the partition created on the sd card should be read-only. Hence my question is, why do you want it to use all of the space of the sd card?

Re: Archiso resize image

The reason I want to use all diskspace or at least much more than the current size, is that 256M is too small to install extra packages like Xorg, Openbox,..

Re: Archiso resize image

A live system is something else, is not like a normal installation. It is read-only and can't be changed.
