Better to just add the variable to the kernel command line.. any XX=something string on the command line is set as environment variables to init.
but it seems the environment is just discarded before running what is in inittab (I'm not sure, I should read the sources later).
It is not, but mingetty/login cleans up the environment on interactive logins. Many other commands is also very restrictive about what is preserved in the environment when starting childprocesses so relying on LD_ASSUME_KERNEL to be globally set for all processes in the whole system is generally not a good idea.. (very hard to guarantee).
sysvinit should have a way to add a variable to the environment. Can it be done in intitab?
Not that I know of. But as the environment can be specified on the kernel command line this isn't really needed.
# This module parses /etc/environment (the standard for setting # environ vars) and also allows you to use an extended config - Do they mean standard in Debian?
No idea what stadard they refer to. It is not in the UNIX standard from what I can see.
