redirecting /tmp

2004-03-04 Thread Robey Holderith
I'm trying to find a way to set an environmental variable so that the 
system will use /usr/tmp or something instead of /tmp as a temporary 
directory.

The story is that I was attempting to change the size of /usr remotely. 
 I backed up all the data and then copied the bare necessities over to 
/tmp then changed fstab so the drive formerly known as /usr was never 
mounted and /tmp was mounted as /usr.  Great! it worked... but now su 
isn't working... because now /tmp is 755.

Any insights are welcome.

Some utilities will pay attention to the TMPDIR environment variable.

However, things that run setuid or setgid will probably avoid
looking at environment variables.  You may have painted yourself
into a corner here, and will need to be at the machine to log in
as root.

That's kinda what I figured.  Ah well, the night is quickly disappearing 
so it looks like I might as well give up until tomorrow when something 
can be done.

Thanks
