net-firewall/iptables: multiple fixes for runscript
- We are now passing iptables "--wait" option to every iptables command which needs to aquire a lock. [Bug 501710] - In addition, "--wait" (IPTABLES_LOCK_WAIT_TIME) and "--wait-interval" (IPTABLES_LOCK_WAIT_INTERVAL) is now configurable via /etc/conf.d/{iptables,ip6tables}. - We are now only installing one runscript and now using a symlink for the ip6tables runscript. - Error detection improved/added. Closes: https://bugs.gentoo.org/501710 Package-Manager: Portage-2.3.52, Repoman-2.3.12 Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
