-.Sh NAME
-.Nm bootfs
-.Nd boot-time module file system
-.Sh DESCRIPTION
-The
-.Nm
-file system is a read-only file system that provides access to any
-boot-time modules that were passed in to the system loader which were
-tagged with the type
-.Em file .
-.Nm
-does not display any boot-time modules that were tagged as type
-.Em hash
-or type
-.Em rootfs .
-If modules with duplicate names and paths are specified, only the first
-such entry will be present in the file system and a counter will be
-incremented to indicate that a duplicate entry was found, but is not
-present into the file system.
-If a module's name only consists of invalid characters, such as
-.Sq . ,
-.Sq .. ,
-or
-.Sq / ,
-then the module will not be present in the file system and a counter
-will be incremented to indicate that this has occurred.
-In both cases, diagnostic information is available through the kstats
-facility.

-Determining if collisions or invalid names are present
-.Pp
-To determine if any boot-time modules were not created due to collisions
-or invalid names, enter the following command:
-.Bd -literal -offset indent
-# kstat -m bootfs
-module: bootfs instance: 1
-name: bootfs class: fs
- crtime 236063.651324041
- nbytes 8749355
- ndirs 3
- ndiscard 0
- ndup 0
- nfiles 2
- snaptime 236063.651324041
-.Ed
-The field
-.Fa ndiscard
-lists the number of boot-time modules that were discarded due to naming
-conflicts.
-The field
-.Fa ndup
-lists the number of duplicate entries that were found and therefore not
-displayed in the file system.
