OSG Version 1.0.1 Release

The Open Science Grid Operation Center (GOC), OSG Integration Team,
and VDT are pleased to announce the availability of OSG Version 1.0.1
of the OSG middleware stack. Documentation for the OSG release can be
found at https://twiki.grid.iu.edu/bin/view/ReleaseDocumentation/.

Please see the "Why Upgrade?" document at https://twiki.grid.iu.edu/twiki/bin/view/ReleaseDocumentation/WhyUpgrade
for details about what has been added and changed from version 1.0.0
to 1.0.1.

This VDT update is provided as an incremental update. As most of you
know, incremental updates have proven to be troublesome in the past.
We believe this update to be significantly better and more likely to
succeed, but we would like to proceed with caution.

We would like a couple of patient, willing system administrators to
try out the new update process and provide us feedback. (Are you one
of them?) Until then, we will consider the update process to be beta
quality. We'll note here when it leaves beta. There is no harm in not
taking this update immediately if you are not willing to try it out
right away.

Incremental updates (whether done with the new system, or by hand with
Pacman as we used to recommend) are likely to fail if any of a few
conditions are true. Here are the signs you should be aware of:

1) Did you install the VDT from more than one VDT cache? (Look in
$VDT_LOCATION/trusted.caches to see if there is more than one VDT URL
listed there.) Or did you install from more than one OSG cache? If you
are unsure, mail your trusted.caches file to vdt-support@opensciencegrid.org
, and we'll help you out.

2) If you run services (like a CE), did you install as anything other
than root? There are some cases where this might cause problems.
Client installations should be fine.

3) Did you install OSG 1.0 before its official release?

4) Did you install a versionsed ce package. That is, when you run
"pacman -lc", do you see a package named "ce" (which is good) or a
package named ce-1.0.0 (which is bad.)

If you answered yes to any of these questions, you're better off doing
a fresh installation.

We'd like to thank the members of the OSG ITB and VTB teams for the
effort they've put into getting this release ready.
