The only Linux-compatible tool to manage NVRAM settings is the command-line-driven nvramtool utility, which is not exactly user-friendly and requires shell access to use.

From what I understand, some time in the past there was a Linux-compatible Text-mode User Interface (TUI) to set NVRAM options; this eventually became the nvramcui payload. I would like to see a Linux-based TUI NVRAM management tool made available again; this tool should read the option table and allow the user to change NVRAM settings.
