That depends on the version. In early/mid 2010 (IIRC) dpkg went through several variations to find a call method that didn't suck. For users, IIRC that means that Debian ≤5 did it one way, Debian ≥6 does it a different way, and Ubuntu 10.04 does it a third way, because it snapshotted dpkg halfway through the transition. strace will confirm how YOUR dpkg behaves, of course. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
