An ubuntu 10 box reports:
Linux mehet 2.6.32-24-generic #43-Ubuntu SMP Thu Sep 16 14:17:33 UTC
2010 i686 GNU/Linux

and "uname -r" from a quick selection of RedHat ES & CentOS boxes


Actually for RedHat derived systems I think the ([a-z].*)$ part is
probably the most useful identifier, or at least worth retaining. a
system which is el5 vs el4 is a more important difference than kernel

For RedHat derived Linux the OS version should probably chop out
/-[^a-z]*(?:\.[a-z])/ (the minor kernel version), and potentially for
ubuntu and debian at least /-.*(?:-)/. Fortunately those two are safe
to run on the "other" format uname -r :)
