.SH "NAME"
systemd-sysv-generator \- Unit generator for SysV init scripts
.SH "SYNOPSIS"
.PP
/lib/systemd/system\-generators/systemd\-sysv\-generator
.SH "DESCRIPTION"
.PP
systemd\-sysv\-generator
is a generator that creates wrapper \&.service units for
\m[blue]\fBSysV init\fR\m[]\&\s-2\u[1]\d\s+2
scripts in
/etc/init\&.d/*
at boot and when configuration of the system manager is reloaded\&. This allows
\fBsystemd\fR(1)
to support them similarly to native units\&.
.PP
\m[blue]\fBLSB headers\fR\m[]\&\s-2\u[2]\d\s+2
in SysV init scripts are interpreted, and the ordering specified in the header is turned into dependencies between the generated unit and other units\&. The LSB facilities
"$remote_fs",
"$network",
"$named",
"$portmap",
"$time"
are supported and will be turned into dependencies on specific native systemd targets\&. See
\fBsystemd.special\fR(7)
for more details\&.
.PP
Note that compatibility is quite comprehensive but not 100%, for more details see
\m[blue]\fBIncompatibilities with SysV\fR\m[]\&\s-2\u[3]\d\s+2\&.
.PP
SysV runlevels have corresponding systemd targets (runlevel\fIX\fR\&.target)\&. The wrapper unit that is generated will be wanted by those targets which correspond to runlevels for which the script is enabled\&.
.PP
\fBsystemd\fR
does not support SysV scripts as part of early boot, so all wrapper units are ordered after
basic\&.target\&.
.PP
systemd\-sysv\-generator
implements
\fBsystemd.generator\fR(7)\&.
