.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
library translates the puffs protocol to the kernel vfs protocol and
|
|
back again.
|
|
It can therefore be used to mount and run kernel file system code as
|
|
a userspace daemon.
|
|
.Pp
|
|
Calling the library interface function mounts the file system and,
|
|
if succesful, starts handling requests.
|
|
The parameters are handled by
|
|
.Fn ukfs_mount
|
|
(see
|
|
.Xr ukfs 3 ) ,
|
|
with the exception that
|
|
.Fa mountpath
|
|
and
|
|
.Fa puffs_flags
|
|
are handled by
|
|
.Xr puffs 3 .
|
|
.Pp
|
|
The following environment variables affect the behaviour of puffs.
|
|
They are useful mostly for debugging purposes.
|
|
The flags are environment variables because typically the command line
|
|
arguments to
|
|
.Nm
|
|
utilities are parsed using versions not aware of possible puffs flags:
|
|
for example, the
|
|
.Xr rump_cd9660 8
|
|
arguments are really parsed by
|
|
.Xr mount_cd9660 8 .
|
|
.Bl -tag -width "XXXP2K_NODETACH"
|
|
.It Dv P2K_DEBUG
|
|
Do not detach from tty and print information about each puffs operation.
|
|
.It Dv P2K_NODETACH
|
|
Do not detach from tty.
