'exit 1' is not optimal for two reasons: 1) Code is hard to read; it is not obvious that it means 'defer what follows to first boot'. 2) Worse, this hides actual errors in the scriptlets; there is no difference between scriptlet failing because it's intended to be run on target and scriptlet failing because there's a bug or a regression somewhere. The new, supported way is to place the code that has to run on target into pkg_postinst_ontarget(), or, if a more fine-tuned control is required, call 'postinst-intercepts defer_to_first_boot' from pkg_postinst() to explicitly request deferral to first boot.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
