I made the following temporary changes in net-analyzer/mtr-0.87 ebuild : * removed fcaps * added postinst ewarn and elog (like pkgsrc style) diff: http://pastebin.com/AJJkpa7r
Created attachment 453146 [details] modified mtr ebuild
I can confirm it, but IMHO the problem isn't fcaps usage per se, but the fact that it's used incorrectly - it should use relative path, not an absolute one. Can you test that this small change fixes the issue in your use case? It fixes the issue for me. -FILECAPS=( cap_net_raw /usr/sbin/mtr ) +FILECAPS=( cap_net_raw usr/sbin/mtr )
that looks plausible to me
I've pushed this to -r1, and added a message like Emre suggested in pkg_postinst.
