.Sh NAME
.Nm rc-update
.Nd add and remove services to and from a runlevel
.Sh SYNOPSIS
.Nm
.Op Fl s , -stack
.Ar add
.Ar service
.Op Ar runlevel ...
.Nm
.Op Fl s , -stack
.Ar delete
.Ar service
.Op Ar runlevel ...
.Nm
.Op Fl u , -update
.Op Fl v , -verbose
.Ar show
.Op Ar runlevel ...
.Sh DESCRIPTION
OpenRC uses named runlevels.  Rather than editing some obscure
file or managing a directory of symlinks,
.Nm
exists to quickly add or delete services to and from from different runlevels.
All services must reside in the
.Pa /etc/init.d
or
.Pa /usr/local/etc/init.d
directories.
They must also conform to the OpenRC runscript standard.
.Pp
.Bl -tag -width "Fl a , -delete service"
.It Ar add Ar service
Add the
.Ar service
to the
.Ar runlevel
or the current one if none given.
Services added to the boot runlevel must exist in
.Pa /etc/init.d .
.It Ar delete Ar service
Delete the
.Ar service
from the
.Ar runlevel
or the current one if none given.
.It Ar show
Show all enabled services and the runlevels they belong to.  If you specify
runlevels to show, then only those will be included in the output.
.It Fl v , -verbose
Show all services.
.It Fl u , -update
Forces an update of the dependency tree cache.
This may be needed in the event of clock skew (a file in /etc is newer than the
system clock).
.El
.Pp
If the
.Fl s , -stack
option is given then we either add or remove the runlevel from the runlevel.
This allows inheritance of runlevels.
