Hi David, I think that part of the problem is the unclear/vague
description of filters (eg: "plain" filter vs global_filter). In other
words, maybe the real problem is a documentation one.
For example: am I right saying that global_filter were introduced as a
"fail-safe" mechanism to protect udev & the likes by
command-line-overwritten "plain" filter directive?
If so, I am not sure the comment in lvm.conf fully convey this message
(and I can not find much on man pages, also). If not, and I am wrong
about filter vs global_filter, then, well, this somewhat proves the
point above :)
