OK, doing it with the -f at the end works.
However, what I am trying to figure out is if ln is permanent. In other
words, now that I have created the hard link, will resolv.conf in the
chroot environment always automatically be changed to whatever
the resolv.conf in /etc becomes? I read the man page and the "info
coreutils" thing as well, and there was not a word about whether
the link was permanent.
This is a laptop, so naturally it is shut down and restarted over and
over in different locations, using ethernet-to-cable at home, and any
of half a dozen different wifi locations while away from home. Some
of those wifi locations (e.g., the one at the university) require me to
log in. The procedure to log in is to open your browser and try to go
somewhere. At that point the university's NoCat comes up and I
enter my student ID and password, and it lets me in, and then
proceeds to open the page I was attempting to reach. Currently I
can do this with the Firefox installed in the 64-bit world, but I'd like
to be able to do this using the 32-bit Firefox I installed in chroot.
Plus, I don't want to have to open a terminal and type the ln
command each time. I just want it all automated so it just "works."
Thanks for the info.
