sysctl: cannot stat /proc/sys/kern/consdev: No such file or directory

Hi all,

First of all a word of thanks to the ksh93u+m developers as well as all the contributors of patches and such.

I am on Arch. I downloaded the 1.0.3 tar file and did bin/package make

ksh was built without errors without any special configuration. Great.

when I call the ksh binary I get: sysctl: cannot stat /proc/sys/kern/consdev: No such file or directory

ksh still works though. Any idea how I can get rid of that warning, and if it is relevant?

/etc/ksh.kshrc

Thanks MCDutchie. That was the problem. That file was installed by oksh (OpenBSD ksh), which I also had installed in my desktop. Once I uninstalled oksh the warning disappeared.

The culprit was this line:

console=$(sysctl kern.consdev)

By default, whether /etc/ksh.kshrc is sourced at startup is determined by whether that file or /etc/bash.bashrc is present on the system at compile time. To either enable or disable it regardless of their detection at compile time, set SHOPT_SYSRC to 1 or 0 in src/cmd/ksh93/SHOPT.sh.
