Description Andre Robatino 2013-02-04 19:57:36 UTC 
Description of problem:
The checkisomd5 man page currently shows only 2 return values, one for PASS, the other for FAIL or UNKNOWN:

EXIT STATUS
       Program  returns exit status 0 if the checksum is correct, or 1 if the
       checksum is incorrect, non-existent, or check was aborted.

If I'm not mistaken, this makes it difficult to fix bug 891548 (ESC during mediacheck drops to emergency shell rather than continuing with the install). I suggest a third return value for UNKNOWN, so the installer can continue with the install on either PASS or UNKNOWN.

Version-Release number of selected component (if applicable):
isomd5sum-1.0.9-2.fc18

Additional info:
Also see bug 839709 which requests a reassignment of the existing two return values. That's independent of this but should be considered when deciding what the return values should be.
Comment 1 Andre Robatino 2013-03-23 21:08:09 UTC 
Verified that in 19 Alpha TC1, the mediacheck does the right thing for PASS, FAIL, and UNKNOWN. (For the latter, the Esc key lets the install continue.)
