Yes the way custom configs where done was a mistake but there's are easily
avoided in mutators etc by removing the config declaration forcing it into
the main config.
This was more of an issue in UE3 with the multi configs by default but it
was fixed in later builds with the addition of the -configsubdir command
line parameter, so became a total none issue.
Bringing down all servers and updating in one go is often preferred as it
eliminates overhead and keeps total downtime to a minimum.
While it is potentially possible that multi servers writing to the same
file could cause an issue this is generally avoided by the OS locking
semantics and I cant say we've ever seen an issue with it.
In addition to this there are significant benefits to be had with respect
to shared resources and performance when the same physical files are
loaded instead of separate copies of the same file, which decreases vm
usage and increases cache efficiency in turn reducing disk contention.
I do agree its not 100% ideal for games that don't use the latest engine
fixes, but our experience is its definitely workable it not preferable.
