Well, Xen immortalize your name in perpetuity by providing this bash script so it can be included in the tool set. Write less hundred line emails, and instead write more code for peer review.

Except you can't be bothered to read source... Or spend the time to write the aforementioned script which will necessarily teach you a thing or two about the inner workings and events with their outcomes. When you put in the effort the community will no doubt appreciate your newly written documentation. Hop to it, eh?

Umm, "rescue environments" are deliberately designed to be more careful about what they do. Are you comparing a OpenSUSE rescue to a Deb/Ubuntu rescue? Or to a Deb "normal" environment? How long have you been around Linux that you are surprised that very different distributions might have different "defaults"?

man (8) vgchange perhaps? man -k lvm?

They maybe less bitching, more experimenting, more practical experience, more man page reading, more knowledge retention, some B12 supplements perhaps? And stick to the bloody topic - nobody cares that you're put off by BugZilla's sparse interface.
