Can anyone explain how the p2 profile creation in Buckminster differs from that created by an IDE export?
The product generated from "Export Product" has a default "profile.profile" folder under p2/org.eclipse.equinox.p2.engine/profileRegistry/, this contains a .data/ folder, a .lock file and a handful of *.profile.gz files.
When creating via Buckminster/Hudson, I specify a profile name in my buckminster.cspex file, and this creates a correspondingly-named directory, with the same .data/ folder and .lock file, but with fewer, ungzipped, .profile files.
This seems to make the difference between p2 updates working and not for me - if I replace my Buckminster-created profile folder with the one created by the IDE and modify my configuration/config.ini accordingly, my updates work fine, otherwise I get features and plugins that report as updated but with the old contents not replaced on disk.
Thanks!

Hi Bob,
I'm uncertain what you mean by "buckminster created profile". The profile is created when a product
is installed by the p2 director. Are you referring to the "create.product" ant tasks in our RCP
tutorial?

Hi,
I finally got to the bottom of my problem!! I thought I'd better share as I find it incredible that I seem to be the only person having this trouble...
In short, my problems were solved by adding the line:
<arg value="-roaming"/>
to the call to the director app in build/product.ant in my product feature project. Forgive me if I'm stating what everyone else already knew, but this came as something of a revelation to me!
Without this option, it *seems* that a product created via the create.product/create.product.zip examples can only be used successfully on the machine on which it was created, or a machine with file access to the build's working directory, as it *seems* the default profile created contains absolute file paths without the -roaming option passed to the director.
I can see why this would be the case, and the scant documentation on the -roaming option makes sense, but I feel like I'm missing something else here - I can't be the first person the build a p2-enabled product via Buckminster and Hudson following the examples and have it not work as expected?
Confused (but happy) :-S
Bob
