This is new -- just a few months ago the same script was working fine, but
it is failing now in both 7.0 and 6.2.
And 5.x. Or it could just be a changed behaviour of the 7.0 kernel, which
is common to all builds.
This e-mail exchange has left me unclear on what has broken on what versions.
Mikhail, when you say "7.0 and 6.2", do you mean actual 7.0 and 6.2 boxes, or
do you mean the package build environment running on 7.0 on pointyhat as
Kris's followup seems to suggest? And what does "failing now" mean -- a quick
glance at the kernel source in RELENG_5 suggests it started "failing now" a
long time ago?
