This read-create object indicates the storage type (e.g. volatile, nonVolatile, permanent) for this params conceptual row, defaulting to nonVolatile, and per the description a 'permanent' row need not allow write access to its columns. Admins set this to control whether the entry survives a reboot and whether it can be modified or deleted afterward. Setting it to permanent(4) would lock the row against modification and guarantee it isn't lost across a restart.
