During a recent image construction process, I had not left enough space in the target pool to create the boot archive. Unfortunately, bootadm update-archive does not always report a failure if the process that notices the out-of-space condition is the gzip process used to compress the ramdisk. Instead, I saw:

stderr| gzip: stdout: No space left on device
stdout| Creating boot_archive for /rpool/images/work/qemu-ttya-full/a
stdout| updating /rpool/images/work/qemu-ttya-full/a/platform/i86pc/amd64/boot_archive (CPIO)

The program then exited with status zero. The resultant boot_archive file was only 12MB, and most definitely incomplete/corrupt.
