If you use the command in an if/while/until statement, it can fail without
terminating the script, even when the "-e" shell option is set. You might
be able to use something like:
while something; do
if cmd_that_can_fail; then :; else
# Just can check $? if you want
# to know the exact return code.
# Print a warning, but
continue
fi
done

That "warning" seems more like an "error" to me -- the function fails.

Using something like the above you should be able to try to mount the all
entries, print a warning for each one that fails, and then return an
appropriate code to indicate success/partial success/failure.
