    "GNU libsigsegv is a library to handle page faults, which occur when a
program tries to access an unavailable region of memory, in user mode.  By
catching and handling page faults, the program can implement pageable virtual
memory, stack overflow handlers, and so on.")

(file-system-shepherd-services): Provision 'file-system only when file system
services without additional Shepherd requirements are started.

to the file-system record. This field is used for adding additional Shepherd
requirements to a file-system Shepherd service.
