Rather then combining hardlink creation for the geom(8) binary with shared library build, move libraries to src/lib/geom so they are built and installed normally. Create a common Makefile.classes which is included by both lib/geom/Makefile and sbin/geom/Makefile so the symlink and libraries stay in sync. The relocation of libraries allows libraries to be build for 32-bit compat. This also reduces the number of non-standard builds in the system. This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit system out of the box as it will look in the wrong place for libraries unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used for setting up a device which contains a shared secret.
|
|
The secret is shared between the given providers.
|
|
To collect the secret, all providers are needed.
|
|
If one of the components is missing, there is no way to get any useful data from
|
|
the rest of them.
|
|
The first argument to
|
|
.Nm
|
|
indicates an action to be performed:
|
|
.Bl -tag -width ".Cm destroy"
|
|
.It Cm label
|
|
Set up a shared secret device from the given components with the specified
|
|
.Ar name .
|
|
Metadata are stored in the last sector of every component.
|
|
.It Cm stop
|
|
Turn off an existing shared secret device by its
|
|
.Ar name .
|
|
This command does not touch on-disk metadata!
|
|
.It Cm clear
|
|
Clear metadata on the given providers.
|
|
.It Cm dump
|
|
Dump metadata stored on the given providers.
|

Exit status is 0 on success, and 1 if the command fails.
|
|
.Sh EXAMPLES
|
|
The following example shows how to create a shared secret device.
|
|
The secret will be split between a slice on a local disk and a USB Pen drive.
|
|
.Bd -literal -offset indent
|
|
gshsec label -v secret /dev/ada0s1 /dev/da0
|
|
newfs /dev/shsec/secret
|
|
.Ed
|
|
.Pp
|
|
From now on, when the USB Pen drive is inserted, it will be automatically
|
|
detected and connected, making the secret available via the
|
|
.Pa /dev/shsec/secret
|
|
device.
