The bootfs 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 file. bootfs does not display any boot-time
modules that were tagged as type hash or type 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 '.', '..', or '/', 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.
The mount point for the bootfs file system in the global zone.
Example 1 Determining if collisions or invalid names are present
To determine if any boot-time modules were not created due to colli‐
sions or invalid names, enter the following command:
# kstat -mbootfs
module: bootfs instance: 1
name: bootfs class: fs
The field ndiscard lists the number of boot-time modules that were dis‐
carded due to naming conflicts. The field ndup lists the number of
duplicate entries that were found and therefore not displayed in the
