Re: installing packages

[Ben Caradoc-Davies <ben@transient.nz>]

I think those instructions are out of date or not applicable to a USB 
stick (cdrecord is for one of those round plastic CD things from the 
olden days). If I recall correctly, the xorriso step is done by "lb 
build" when assembling the iso.

Just like any other Debian hybrid iso, you can use "dd" as root to write 
the iso image straight to a USB block device:

dd if=live-image-amd64.hybrid.iso of=/dev/sdX bs=4M

where "X" is "c" for the example you give. Just make *bloody* sure that 
you have the right output device file ("of") as the contents are 
overwritten by this command. Plug it in and check with "dmesg" to make 
sure you have the right one. Do not mount the USB stick before running "dd".

When "dd" has finished running, the USB stick should be bootable. The 
hybrid iso image contains the required boot loader and MBR partition 
table. live-build does not support UEFI boot so you will need a BIOS 
that supports MBR boot (legacy or compatibility mode). (UEFI support is 
one key reason for live-wrapper, a completely different package for 
building live images, waiting in the queue for inclusion in the Debian 
archive.)

Kind regards,
Ben.
