We (CentOS) chose to use 4 to be compatable with the dag repo ... and
other 3rd party software. Tao Linux and WhiteBox Linux do the same.
4 (or 3 for CentOS-3.x) will always be the version ... and:
http://mirror.centos.org/centos/4/
Will always point to the latest version of the distro. /4/ will always be
a symlink to the latest version (4.1, 4.2, 4.3, etc.).
If you look at the redhat-release file, you can cat it and get the real
release as well. So, you can use this in a script to get the number you
are looking for:
cat /etc/redhat-release | awk {'print $3'}
and you can use:
rpm -q --qf '%{version}\n' -f /etc/redhat-release
to get a number that is compatable to RHEL's numbering scheme.
