> sysctls [...] not shell-compatible
Say what? "sysctl -w variable=value" is quite shell-friendly. For kernel *configuration*, I think the
sysctl interface made (and still makes!) a lot more sense than the 20 different mechanisms added
"sysctl -a | grep Whatever" is just as good -- perhaps even better -- than recursive grep against
/proc/sys, /sys/, and whatever the new-userspace-interface-of-the-month this month is...
