Hi,
I have been running testing/netctl for a couple of days now and noticed some issues (some of which are not really netctl specific). I thought it might be better to bring them up here, as opposed to flyspray.
1. There used to be a DHCP_OPTIONS variable in netcfg, but it is never mentioned in netctl documentation. Meanwhile, ip_set() in globals, does have DHCPOptions. Was making this variable invisible to the user intentional? It is quite convenient when dealing with buggy DHCP servers (e.g. -d switch for dhcpcd)...
By the capitalization, you can tell that DHCPOptions is intended to be usable in profiles. However, this feature went undocumented because in the past users have made a mess with it. For instance, by backgrounding the daemon. If DHCP servers are buggy, they should be fixed, thats not netctl's fault. However, if you can come up with a piece of documentation that makes users not want to use this variable, I'd love to include it.
2. There is a WPADriver variable whuch is not read if a profile is included in a group by netctl-auto (because profiles are parsed in separate subshells). This a good thing, as different profiles can have incompatible values of WPADriver, but I think it should be included in documentation (it can seriously confuse a user, myself included, who looks at ps auxww).
Your new documentation suggests the same holds for other variables too, but I cannot quickly see which ones. If WPADriver is the only one, I would prefer the suggestion is removed from the documentation ;-).
3. This is the main issue, albeit also present in netcfg. With wpa_supplicant 2.0 and wpa_actiond 1.4 we noticed a sizeable delay when shutting down netctl-auto (resp. net-auto-wireless) in a WPA-EAP environment. This is somehow related to the fact that wpa_actiond is never killed by netctl/netcfg which only terminates wpa_supplicant/dhcp client. The real problem may be in wpa_supplicant, but regardless, netctl/netcfg should properly clean up after itself.
What is the problem, precisely? If wpa_actiond sees the supplicant has disappeared, it quits. In a systemd setting, this all seems perfectly fine, doesn't it?
Pts. (2) and (3) are 'fixed' by the following small patch...
