#10360 Option values read from @files don't invalidate when the file changes Issue created by benjyw Any* option's value can be read from a file, by using

@path/to/file

as the value. A subsystem instance that has such an option is not invalidated when the contents of the file change, so changing the file and then rerunning pants doesn't apply the new value, until you restart pantsd. • Unless it sets

fromfile=False
