[cs631apue] Readlink errors

I'm using readlink to read symlinks to determine their actual target and
print it out as part of the longformat. This seems to work for links I
create but I've run into existing symlinks that don't work and I believe is
a permissions issue.

How are you handling this?

for example if I run "./ls -l /etc/" on my Ubuntu VM....

It works on this...
blkid.tab -> /dev/.blkid.tab


but not on this...

vtrgb -> Could't read link

and many others.

I've had no issues on symlinks I've created so far.

Thoughts?
