create-index option and file location

[uggyuggy]

Hi,

Thank you for the last release !

When using the create-index option

I noticed the ct_index.json is created into the current directory (whatever the location is set into the config file)

$ tail -1 config.yml
    ct_index_file: "/tmp/ct_index.json"
$

$ ./certstream-server-go_1.9.0_linux_amd64 create-index
2026/04/08 17:13:10 config.go:133: Using config file: config.yml
...
2026/04/08 17:13:22 ct-watcher.go:303: Index file saved to ct_index.json

$  ls ct_index.json
ct_index.json
$  ls /tmp/ct_index.json
ls: cannot access '/tmp/ct_index.json': No such file or directory

Suggestion:

As the config file is used (Using config file: config.yml), would it be better to create the index file where the config file tell the file should be located ?
(And keep creating in current directory if there is no ct_index_file setting into the config file)

Fair point, I am currently not using the path from the config. You can manually overwrite it via the --out parameter. It defaults to ./ct_index.json. I'll have it default to the option in the config. Only if neither is set, I'll default to ./ct_index.json. Thanks for reporting.
