[arch-releng] [PATCH 2/2] Use a label when generating the image and pass it to the commandline This will generate a label ARCHISO_$randomstring using the pwgen utility and add this label to the kernel command line. A new label will be generated for each image, so it can be uniquely identified.

[Thomas Bächler]
