My inclination: test the return value of the various set*id calls and if
fail, do g_error().

Thoughts ?


I'd be tempted to make it a g_warning() since Wireshark will
*probably* keep working despite the problem. The general approach
seems sound though.

After thinking about this a bit, I've decided to abort given that if anattempt to reduce privileges fails for some obscure reason, it'sprobably best not to proceed with possibly elevated privileges.
