I'd like to set the FSCK_FORCE_ALL_PARALLEL environment variable so fsck uses it when it runs when the system is coming up. (i.e. after a shutdown -F )

I don't know where to set these sorts of environment variables... /etc/profile.d/* seems to be too late. I tried /etc/sysconfig/init but I don't think that had the desired effect, or my value of 1 was not meaningful to fsck.... the man pages say only that the environment variable affects fsck, it doesn't say that variable needs a specific value.

Where are env variables set if you want them to affect processes that bring the system up, such as these FSCK_* variables?

Thanks
