Thanks. You're point about the overall readability is well taken
James. OTOH (runnin current cooker, rpm-4.2-18mdk),
RPMS # rpm -K --nogpg *.rpm | grep NOT
--nogpg: unknown option
So I removed --nogpg an tried again,
RPMS # rpm -K *.rpm | grep NOT (after a minute or so....)
RPMS #
I take it that since no result was output, that the CDr is OK?
'rpm --help' says that -K just checks package signatures, so maybe
nothin was really done? If so, I suspect md5sum is a better check.
It also has to read the whole CD image. This was on RC2 CD1,
burned with cdrecord -v -eject speed=4 dev=0,0,0 -dao
...and the md5sum from the iso on HDD before, and CDr after
burnin checked. For the original poster, back when I ran cooker
with a dialup and help with ocaissonal cooker CD's from friends, I
often had trouble reading they're burned CDr's. Specially with a
CDrom, tho booting from my burner would often work well enough to
get me thru the install after a few tries. In any event, I believe
your system is just havin trouble with the CD's you were sent.
