I see the mtab symlink with two fresh builds of openSUSE 12.1 from DVD onto physical machines so it's not exclusive to susestudio.

Presumably there is a good reason for doing that

Well, my only idea is to fix the 'df' utility not to print the rootfs information twice. Adding coreutils maintainer to CC. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

this is an issue in OpenSUSE, and it's been fixed in revision 4 of the collectd package in Factory:

https://build.opensuse.org/package/rdiff?linkrev=base&package=collectd&project=openSUSE%3AFactory&rev=4

The .changes file doesn't reference this bug number :-/ Also, can this be backported to 12.2? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
