yes, the scheduler is gone for some time now, we
recently removed the 'dummy' interfaces ...

and both too old for that kernel :)

that's something you want to talk with your distro
maintainers about ...

depends, the kernel advertises a certain API, which
to some degree (as far as mainline permits it) is
backwards compatible (the VCI version below), but
there is no 1:1 relation between VCI version change
and util-vserver version update ...

possible, yes, feasible, no ... mainly because the
matrix is auto generated from the upload server(s)
but if you like to do an extensive version test and
comparison, publish and maintain the results, you
could make your own wiki page for that ...

util-vserver is and always was backwards compatible
over a long range of kernels, of course, without
special configuration you won't be able to use it
on older 2.4 kernels :)

yes, definitely, i.e. unless you pick a broken kernel
like the debian 2.6.26 one, you should be quite fine
even with relatively old kernels and most recent
util-vserver ...
