I'm perfectly fine with that. I'd just like to see no PROCPS_SYSCTL in PTXdist config files at all, which is rather hard because 1) we are importing Busybox' version anyway 2) people won't understand it was removed for their own good ;-) So lets individuals decide and document it. ladis (thinking enlighted autocracy is the only right form of governement) -- ptxdist mailing list ptxdist@pengutronix.de

Then it could be easy to read/write files in /proc/sys directly, unless you found some sysctl entry which does not have its equivalent in /proc/sys. Is it the case? Otherwise, it should be only matter of script(s) modification. ladis -- ptxdist mailing list ptxdist@pengutronix.de

My man page dated 21 Sep 1999 says: sysctl is used to modify kernel parameters at runtime. The parameters available are those listed under /proc/sys/. Procfs is required for sysctl support in Linux. You can use sysctl to both read and write sysctl data. Honestly, I've never got the point of this program. > Carsten can you please add a notice to PTXCONF_PROCPS_SYSCTL's helptext > stating that this is a deprecated interface. I'd commit this patch only after someone would find anything available only via sysctl and meanwhile add notice advicing people to use /proc/sys. ladis -- ptxdist mailing list ptxdist@pengutronix.de

As sysctl was in our firmware for a long time and is still used for older kernels, I added this patch. I will add the comments to the patch, so everyone knows as well. And of course I will remove sysctl from our current dev-firmware asap. Nevertheless I need it for the old projects - all of them are maintained to work with the latest ptxdist version. -- Carsten Schlote signature.asc Description: Dies ist ein digital signierter Nachrichtenteil -- ptxdist mailing list ptxdist@pengutronix.de
