ASF(8) MidnightBSD System Manager’s Manual ASF(8)
asf — add symbol files
asf [−afksx] [modules-path [outfile]]
By default, asf reads kldstat(8) output from standard input and writes to standard output a list of gdb(1) commands to add symbol files from KLDs in subdirectories of the subdirectory modules of the current directory, which is intended to be a kernel build directory. This allows gdb(1) to load the symbols into the debugging environment.
If modules-path is specified, asf uses it for the modules directory instead of the default modules. This is useful when building in a non-standard location (i.e., not /usr/src and /usr/obj).
If outfile is specified, asf writes to it instead of standard output.
The following options modify the function of asf:
When writing to an explicit outfile, append to the file rather than overwriting it.
Instead of trying to simplistically guess the path for each module, perform a traversal in the same way that find(1) does to locate an exact path for each module, no matter where in modules-path it is located.
Instead of reading from standard input, start a kldstat(8) and read the information from it.
Do not prepend a (guessed) subdirectory of the module path.
Normally asf looks for KLDs with names of the form 〈
module 〉.ko.debug. The
−x option tells asf to look for KLDs with names
of the form 〈
The asf utility first appeared in FreeBSD 5.2.

It should be possible to write to an outfile without specifying a module path.
