That code was simply "inspired" from the execlp() code in qtest_init_without_qmp_handshake() ... but g_spawn_sync() sounds like a good alternative here, so I'll try to switch to that one instead.

We already have the code for a boot file in tests/boot-sector.c, so if the genisoimage program is available, we can easily create a bootable CD ISO image that we can use for testing whether our CD-ROM emulation and the BIOS CD-ROM boot works correctly.
