sysctl errors

[frafra]

This is what I see running aide with Docker:

aide_app_1  | sysctl: setting key "net.ipv4.tcp_keepalive_time": Read-only file system
aide_app_1  | sysctl: setting key "net.ipv4.tcp_keepalive_intvl": Read-only file system
aide_app_1  | sysctl: setting key "net.ipv4.tcp_keepalive_probes": Read-only file system

Hi,

Those three messages pertain to the keepalive timer that needs to be set for Psycopg2 to not lose connections to the PostgreSQL database. However, in Docker this seems to be no problem. I will remove these commands upon confirmation, but for now the warnings can simply be ignored.
