After running ./scripts/build, do:
./scripts/astlinux-makeimage -z 256 256 0
This creates an astlinux-xxx.img.gz file with a single FAT16 partition of 256MB.
Burn this image to a CF or USB flash drive:
zcat astlinux-xxx.img.gz | dd of=/dev/sdc bs=64k
(if /dev/sdc is where my system detects the CF… Be very careful to get of= correct…)
If you hadn't used the -z flag, then it would just be:
dd if=astlinux-xxx.img of=/dev/sdc bs=64k
to burn this image onto a CF.
Wait until the 'busy' light on your CF reader stops blinking. Just to be sure, do:
sync
At this point, you may remove your CF and install it into your target system, power up… boot,
and follow New Installation to complete the process.
Note: The above ./scripts/astlinux-makeimage part does NOT work in a virtual machine, which runs as an LXC container (e.g. in Proxmox). You'll need a “real” VM (with full Hardware-Virtualization) for this to work.
