According to Benoit Sigoure on 12/17/2007 1:04 AM:
./torture.at:241: ./config.status --file=-:input </dev/null >/dev/
full
stderr:
/tmp/autoconf/tests/testsuite.dir/at-test-source: line 893: /dev/
full:
Operation not supported
This looks like a tpyo but I checked in the source and it's not,
why not
use something like /nonexistent/whatever?
There's a different between a shell failure in being able to create
the
file (the tool under test isn't even run, because the shell errored
out
beforehand), and a write file when writing to an existing device
that runs
out of space. We really do want the latter, not the former. So the
correct fix is to first check whether /dev/full exists and is
writable,
and if not, skip the test, before proceeding on with the attempt to
redirect tool output into the full device. Coreutils and m4 head both
have tests along those lines, which can be used as an example.
