Since multiple processes can write logs simultaneously, and there is no explicit synchronization between them, logs redirected to stdout may interleave. When logging to the disk file, synchronization is obtained by using a combination of O_APPEND and O_SYNC flags when log file is being opened, which is not possible when <stdout> redirection is in use. So documentation is updated to cleanly notify that this is debug-only feature, not for regular use

the user).

Additional umask to apply to files in the \fBFuseMountName\fR directory.
|
|
The default value of 077 prevents other users on the system from reading
