By default, in the Net-SNMP agent, they are saved dynamically so they
should persist across agent reboots.

The saving-routines are registered in snmplib/snmpusm.c's
init_usm_conf() function (which is called from the agent's mib
modules).  Note the 'usm_store_users()' callback that is registered.
See that function, also in snmplib/snmpusm.c, for where the usm users
get saved at shutdown.
