Check permissions before rewrite

[vlaborie]

Hello,

I try to run Warpgate in Kubernetes, my warpgate.yml is a Kubernetes ConfigMap mounted as a read-only volume.

My warpgate.yml is mounted with '0600' unix right but i have this error on start:

13.03.2024 08:35:27  INFO warpgate::commands::run: Warpgate version=0.9.1
13.03.2024 08:35:27 ERROR warpgate: Fatal error error=Could not secure config

Caused by:
    Read-only file system (os error 30)

Could you add a permissions check before trying to rewrite permissions and not rewrite perms every time if it is not needed ?

Thank's.
