OpenWrt x86 64

• Download latest generic-ext4-combined.img.gz for PC BIOS systems here
  • Disk image uses a single read-write ext4 partition without a read-only squashfs root filesystem. As a result, the root partition can be expanded to fill a large drive (e.g. SSD/SATA/mSATA/SATA DOM/NVMe/etc).
• Download latest point release live image for Kali here
• Boot the system without an OS using the Kali live image
• Unpack image $ gunzip openwrt-*.img.gz
• Identify disk (to replace sdX in the following command below) $ lsblk
• Use dd to write image to /dev/sdX $ sudo dd if=openwrt-22.03.3-x86-64-generic-ext4-combined.img of=/dev/sda bs=1M
• Use gparted to expand the rootfs to fill out the remaining size of the disk (/dev/sdX2 partition)
