What I did

Right now config reload -l is getting failed due to below error.

admin@lnos-x1-a-asw03:~$ sudo config reload -l
Clear current config and reload config from the default config file(s) ? [y/N]: y
Traceback (most recent call last):
  File "/usr/local/bin/sonic-cfggen", line 431, in <module>
    main()
  File "/usr/local/bin/sonic-cfggen", line 326, in main
    _process_json(args, data)
  File "/usr/local/bin/sonic-cfggen", line 236, in _process_json
    with open(json_file, 'r') as stream:

                    [-S [HWSKU_CONFIG]] [-y YAML] [-j JSON] [-a ADDITIONAL_DATA] [-d] [-H] [-s REDIS_UNIX_SOCK_FILE]

                    [--print-data | -w | -K KEY]
sonic-cfggen: error: argument -k/--hwsku: expected one argument

I guess the problem is here in sonic-utilities repo. If user does not provide filename with config reload -l, command = "{} -j {} -v DEVICE_METADATA.localhost.hwsku".format(SONIC_CFGGEN_PATH, filename) will not provide cfg_hwsku i.e. hwsku parameter as it should which will later cause problem here command = "{} -H -k {} --write-to-db".format(SONIC_CFGGEN_PATH, cfg_hwsku) as hwsku is not available around that time.

that's why we notice errors like No such file or directory: 'None' as pasted in this issue.

File "/usr/local/bin/sonic-cfggen", line 328, in main
    _process_json(args, data)
  File "/usr/local/bin/sonic-cfggen", line 236, in _process_json
    with open(json_file, 'r') as stream:
FileNotFoundError: [Errno 2] No such file or directory: 'None'

How I did it

To Fix the issue, moved the part where the code gets cfg_hwsku command = "{} -j {} -v DEVICE_METADATA.localhost.hwsku".format(SONIC_CFGGEN_PATH, file) to the same location it needed as we get filename by default.

How to verify it

Before the Fix
