cdrtools bug fix update

Updated cdrtools packages that resolve a number of bugs are now
available for Red Hat Enterprise Linux 4.

The cdrtools packages provide a collection of CD-ROM and DVD utilities.

These updated packages fix the following bugs:

* the cdrecord program burned DVD+R and DVD+RW discs in such a way that
they were not able to be mounted. When trying to burn a DVD+R or DVD+RW
disc with cdrecord, the following message appears:

Please use growisofs from dvd+rw-tools or cdrecord-Pro for DVD+R/DVD+RW.

Users are advised to use the growisofs utility (or cdrecord-Pro) from the
"dvd+rw-tools" package for burning DVD+R and DVD+RW discs.

* the mkisofs utility was unable to handle directories in which the ".."
parent directory entry preceded the "." directory entry. Running mkisofs on
such a directory caused the following error message to be displayed:

Unknown file type (unallocated) /[usr]/[share]/.. - ignoring and continuing

With these updated packages, mkisofs correctly handles directories in which
the ".." directory precedes ".", thus resolving the problem.

* running the "mkisofs" utility with the "-no-emul-boot" switch when an
image argument was not specified with the "-b" boot option caused mkisofs
to segmentation fault. With these updated packages, using the
"-no-emul-boot" switch without a corresponding "-b" option causes the
following warning to be displayed:

Missing boot image name, use -b option

Users of cdrtools are advised to upgrade to these updated packages, which
resolve these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
