Hello Martin,

Thanks for the pointers. I abandoned my Linux efforts, too many issue
and things to learn no time now. My goals could be satisfied by an
OpenBSD VM and it is much better than most Linuxes ;). I have been
swimming against the current (read using things/software/apis/os/tools
etc. when people said it is not what is supposed to be done) but as of
late I find it more relaxing going with it ;).

Virtualization is such a ... mess which like everything else in our
lives nowadays is designed to cover another mess ... I want to run Linux
software on OpenBSD because I don't want to dedicate a machine to Linux
and want to upgrade or run the version I want until I want ... I should
be free to make that choice because of "I", sarcastic here, problem is
CPU vendors and OS developers have to jump some hoops and add some
features to make it happen ... and then things happen that the I does
not like.

Thanks for adding this info albeit to the wrong thread, I read it
because I like Alpine and was thinking of it myself, but they don't have
a ready console install version do they?

Cheers,

George
