Ugh. Whatever you do, don't use that, it's by far the worst way to try to identify a distribution. To quote the manpage: "The file /etc/issue is a text file which contains a message or system identification to be printed before the login prompt." - it can contain any arbitrary message put there by sysadmins instead of whatever the distro makers happened to stuff in there. > > Is there a good, or at least better, way to set a "distribution" > variable for use in scripts or in yum itself?

[pmatilai@weasel ~]$ lsb_release -a LSB Version: 1.3 Distributor ID: FedoraCore Description: Fedora Core release 4 (Stentz) Release: 4 Codename: Stentz ..is as portable as it gets AFAIK. You didn't mention what exactly are you using the info for so difficult to say if that's the best way to accomplish that. - Panu -
