# symlinkify
|
|
|
|
Due to the levels of indirection introduced by mergerfs and the
|
|
underlying technology FUSE there can be varying levels of performance
|
|
degradation. This feature will turn non-directories which are not
|
|
writable into symlinks to the original file found by the `readlink`
|
|
policy after the mtime and ctime are older than the timeout.
|
|
|
|
**WARNING:** The current implementation has a known issue in which if
|
|
the file is open and being used when the file is converted to a
|
|
symlink then the application which has that file open will receive an
|
|
error when using it. This is unlikely to occur in practice but is
|
|
something to keep in mind.
|
|
|
|
**WARNING:** Some backup solutions, such as CrashPlan, do not backup
|
|
the target of a symlink. If using this feature it will be necessary to
|
|
point any backup software to the original filesystems or configure the
|
|
software to follow symlinks if such an option is
|
|
available. Alternatively, create two mounts. One for backup and one
|
|
for general consumption.
