33  * Each general-purpose state structure is named by an FMRI - the FMRI of the
34  * piece of hardware being described.  FMRIs are nvlists, and thus require
35  * special handling if they are to be persisted along with the general-purpose
36  * buffer.  The cmd_fmri_t manages the FMRI, both in packed (persistable) and
37  * unpacked formats.  The packed FMRI is stored in a separate buffer (named by
38  * the fmri_packnm member), from which it can be unpacked on restore.
39  *
40  * Data structures:
41  *
42  *     ,--------.
43  *     |G.P.    |
44  *     |buffer  |
45  *     |,-------|         ,-------------.
46  *     ||fmri_t |   ----> |packed nvlist|
47  *     |`-------|         `-------------'
48  *     `--------'
49  *
50  * The buffer for the general purpose buffer is named and stored independently.
51  * This subsystem creates and manages the packed nvlist buffer, using a name
52  * provided by the caller.
