I always specify a tce directory on the kernel line in my bootloader and, when I want to test stuff on a base system, I just add "base norestore" onto the end of the kernel line, leaving the tce=... setting intact. But after booting with "base norestore", /etc/sysconfig/tcedir does -not- point where I told it to - it points to /tmp/tce.
I know I could script around this in bootsync.sh, but what I really mean by "base norestore" is "I knew what I was talking about when I told you where to find the tce directory, I just don't want to load anything from it this time".
Does this sound reasonable? Am I being dumb?
Maybe a thought for 5.0?
