The following patch works around it:

The error is due to fmt.Fscanf in (*bootstrapStream).build:
output := new(bytes.Buffer)
err := runInTarget(nil, output, rootDir, packagerPathname,
"show-size-multiplier")
if err != nil {
return nil, err
}
sizeMultiplier := uint64(1)
nScanned, err := fmt.Fscanf(output, "%d", &sizeMultiplier)
... trying to parse the following error from mount as an integer:
mount: none is already mounted or /sys busy
none is already mounted on /proc
none is already mounted on /sys
none is already mounted on /proc
