@mechalas Please see the NFS section of the .fogsettings documentation, and set it to not overwrite your exports file:

@Sebastian-Roth there appears to be an /etc/exports.d
functionality I’d suggest looking into. Maybe fogs config can be put into its own separate file:

Because this would be an improvement and not a break-fix, I’d suggest backlogging this until more pressing things are sorted.
