.SH "NAME"
systemd-fstab-generator \- Unit generator for /etc/fstab
.SH "SYNOPSIS"
.PP
/lib/systemd/system\-generators/systemd\-fstab\-generator
.SH "DESCRIPTION"
.PP
systemd\-fstab\-generator
is a generator that translates
/etc/fstab
(see
\fBfstab\fR(5)
for details) into native systemd units early at boot and when configuration of the system manager is reloaded\&. This will instantiate mount and swap units as necessary\&.
.PP
The
\fIpassno\fR
field is treated like a simple boolean, and the ordering information is discarded\&. However, if the root file system is checked, it is checked before all the other file systems\&.
.PP
See
\fBsystemd.mount\fR(5)
and
\fBsystemd.swap\fR(5)
for more information about special
/etc/fstab
mount options this generator understands\&.
.PP
systemd\-fstab\-generator
implements
\fBsystemd.generator\fR(7)\&.
.SH "KERNEL COMMAND LINE"
.PP
systemd\-fstab\-generator
understands the following kernel command line parameters:
.PP
\fIfstab=\fR, \fIrd\&.fstab=\fR
.RS 4
Takes a boolean argument\&. Defaults to
"yes"\&. If
"no", causes the generator to ignore any mounts or swaps configured in
/etc/fstab\&.
\fIrd\&.fstab=\fR
is honored only by initial RAM disk (initrd) while
\fIfstab=\fR
is honored by both the main system and the initrd\&.
.RE
.PP
\fIroot=\fR
.RS 4
Takes the root filesystem to mount in the initrd\&.
\fIroot=\fR
is honored by the initrd\&.
.RE
.PP
\fIrootfstype=\fR
.RS 4
Takes the root filesystem type that will be passed to the mount command\&.
\fIrootfstype=\fR
is honored by the initrd\&.
.RE
.PP
\fIrootflags=\fR
.RS 4
Takes the root filesystem mount options to use\&.
\fIrootflags=\fR
is honored by the initrd\&.
.RE
.PP
\fImount\&.usr=\fR
.RS 4
Takes the
/usr
filesystem to be mounted by the initrd\&. If
\fImount\&.usrfstype=\fR
or
\fImount\&.usrflags=\fR
is set, then
\fImount\&.usr=\fR
will default to the value set in
\fIroot=\fR\&.
.sp
Otherwise, this parameter defaults to the
/usr
entry found in
/etc/fstab
on the root filesystem\&.
.sp
\fImount\&.usr=\fR
is honored by the initrd\&.
.RE
.PP
\fImount\&.usrfstype=\fR
.RS 4
Takes the
/usr
filesystem type that will be passed to the mount command\&. If
\fImount\&.usr=\fR
or
\fImount\&.usrflags=\fR
is set, then
\fImount\&.usrfstype=\fR
will default to the value set in
\fIrootfstype=\fR\&.
.sp
Otherwise, this value will be read from the
/usr
entry in
/etc/fstab
on the root filesystem\&.
.sp
\fImount\&.usrfstype=\fR
is honored by the initrd\&.
.RE
.PP
\fImount\&.usrflags=\fR
.RS 4
Takes the
/usr
filesystem mount options to use\&. If
\fImount\&.usr=\fR
or
\fImount\&.usrfstype=\fR
is set, then
\fImount\&.usrflags=\fR
will default to the value set in
\fIrootflags=\fR\&.
.sp
Otherwise, this value will be read from the
/usr
entry in
/etc/fstab
on the root filesystem\&.
.sp
\fImount\&.usrflags=\fR
is honored by the initrd\&.
