How many other tags can I store with sneep?
That depends on what else is in the nvramrc, the length of the tags and values, and on the specific hardware platform. Different platforms use different EEPROM chips. The smallest eeprom we have seen (300 bytes) could store 10 sneep tag/value pairs if the average size of each was approximately 30 bytes. Newer machines tend to have a larger eeprom, around 4000 bytes. If there are other items in the nvramrc (e.g “devalias” device alias entries) these reduce the amount of space available for sneep tags. sneep limits your total nvramrc usage to a conservative amount appropriate for your hardware platform, unless more than that is already in use. If that is the case, then you can use no more than is already in use, unless you override this safety limit with the “-F” (force) option.
