assumes host is x86

[jonassmedegaard]

If I read the code correctly , it checks if host is a 32-bit architecture, and if it is then it expects to be able to run i386 code fetched online.

In other words, it seems bootiso will fail when running on ARMv7 or MIPSEL or other atchitectures.

It checks first if the binary available on kernel.org is 32 or 64 bits, and then checks for host architecture. But indeed, the remote feature is not available on non-x86 / x64 architectures such as ARM.

This limitation is mentioned in the man. We could implement a "graceful degradation" strategy by disallowing the remote feature on other architectures explicitly.
