Subject: [PATCH procps 1/3] add --system switch Subject: [PATCH 1/3] add --system switch
instead of requiring distributions to construct a loop around sysctl instead of requiring distributions to construct a loop around sysctl
in boot scripts just scan a set of default directories if the --system in boot scripts just scan a set of default directories if the --system
switch is used. switch is used.
Config files are applied in alphabetic order of their base name.
Each base name is only applied once according to the directory
preference. /etc/sysctl.conf is always applied last.
