| # This bbclass provides basic functionality for user/group settings. |
| # This bbclass is intended to be inherited by useradd.bbclass and |
| # extrausers.bbclass. |
| |
| # The following functions basically have similar logic. |
| # *) Perform necessary checks before invoking the actual command |
| # *) Invoke the actual command, make retries if necessary |
| # *) Error out if an error occurs. |
| |
| # Note that before invoking these functions, make sure the global variable |
| # PSEUDO is set up correctly. |
