- Support specifying an io.Reader as Input. Use this instead of Path for reading Resources.
- Default io.Writer to os.Stdout if no Path is specified
- Default io.Reader to os.Stdin if no Path is specified
- Support specifying an explicit list of Functions.
If specified, use these in place of reading from the Input or Directory source by default.
In, pull #1822 mount logic was refactored where the default
mount using zero-value no longer makes sense and leads to
this failure:
"invalid argument "type=,src=,dst=:ro" for "--mount" flag: type is
required"
I think the intent here was to remove default mount.
