generate hints for the kernel loader
utility is used to generate hint files
which list modules, their version numbers, and the files that contain them.
These hints are used by the kernel loader to determine where to find a
particular KLD module.
A separate hint file is generated for each directory listed on the command line
that contains modules. If no hint records are generated for a particular
directory, no hint file is created, and the preexisting hint file (if there
was one in that directory) is removed.
The following options are available:
- Recurse into subdirectories.
- Do not generate a hint file, but print module metadata on
- Specify a different name for the hints files than
- Operate in verbose mode.
To build hint files for both standard and add-on modules:
kldxref /boot/kernel /boot/modules
To build hint files for all installed kernels:
kldxref -R /boot
