<cw> viro: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.13-rc5/2.6.13-rc5-mm1/broken-out/pivot_root-circular-reference-fix-2.patch
<viro> WTF?
<cw> -EWTFWTF?
<viro> akpm: patch is an utter bullshit
<viro> akpm: we are _NOT_ allowing to change namespace root
<viro> not with pivot_root(), not with anything else
<viro> moreover, I distinctly remember having such check in sys_pivot_root()
<viro> where the hell had it gone?
<cw> viro: what about depricate pivot_root since it's the source of so much angst? (i used it myself and im not sure how to avoid it here but there must be a way)
* viro goes to look through history
<viro> LARTs are needed, apparently
<olaf> or -einval for pivot_root on rootfs (if thats detectable)
<viro> of course it is
--> plai_ (~plai@gatekeeper.intransa.com) has joined #kernel
<viro> sigh...
<viro> what we should do is prohibit any mount activity on detached vfsmounts, *period*
<viro> akpm: please, consider that patch in its current form strongly vetoed
<crlf> viro: if you restructure vfsmount trees to not depend on namespaces, there's no need for that restriction
<akpm> viro: OK.  You were cc'ed on it a lot at the time..
