2017-08-04make 17 state-changing execing applets (ex: "nice PROG ARGS") noexecDenys Vlasenko
The applets with "<applet> [opts] PROG ARGS" API very quickly exec another program, noexec is okay for them: chpst/envdir/envuidgid/softlimit/setuidgid chroot chrt ionice nice nohup setarch/linux32/linux64 taskset cttyhack "reset" and "sulogin" applets don't have this form, but also exec another program at once, thus made noexec too.

2017-03-13runit: fix chpst -n -N -u USERDenys Vlasenko
busybox's chpst first switches user/group and then tries to call nice(). Once the root priviledges are dropped, process priority can only be lowered. So negative nice values don't work anymore. Upstream version of chpst correctly calls nice() before switching user. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
