I have a single Linux host server with several Virtualbox guest VM's.  I've been attempting to move everything possible from the host to one of the guests.

One of the last holdovers is Firebird.  The reason is I use NFS to mount host folders within the guest for critical data - and the .fdb certainly counts.  My goal is to have all critical data stored on a host partition or folder - not in guest virtual drives - which I (possibly mistakenly) believe improves performance and recoverability.

So for my use case - I have a single Firebird server instance.  There will never be more than one copy of Firebird running.  All write and 99.99% read access to the .fdb would be through that single Firebird instance (except for automated remote backup operations running on the host).

Am I "safe", possibly even correct, in using RemoteFileOpenAbility in this use case?
