I was asked to add Void Linux to the list of OSes available to install via PINN (a fork of NOOBS) on the Raspberry Pi.
As you have a .tar.xz install format I thought it would be easy, but since PINN/NOOBS uses bsdtar it failed with several of the following warnings (which were treated as errors):
bsdtar: Pathname can't be converted from UTF-8 to current locale.
Could I ask which tar tool you have used to archive the OS installation and which tar format it uses (pax, gnu, ustar etc)?
Are there any requirements to keep this format, or could it be changed to one compatible with NOOBS/PINN?
