.SH "NAME"
arch-chroot \- enhanced chroot command
.SH "SYNOPSIS"
.sp
arch\-chroot [options] chroot\-dir [command] [arguments\&...]
.SH "DESCRIPTION"
.sp
arch\-chroot wraps the \fBchroot\fR(1) command while ensuring that important functionality is available, e\&.g\&. mounting \fI/dev/\fR, \fI/proc\fR and other API filesystems, or exposing \fBresolv.conf\fR(5) to the chroot\&.
.sp
If \fIcommand\fR is unspecified, arch\-chroot will launch \fB/bin/bash\fR\&.

.sp
The target chroot\-dir \fBshould\fR be a mountpoint\&. This ensures that tools such as \fBpacman\fR(8) or \fBfindmnt\fR(8) have an accurate hierarchy of the mounted filesystems within the chroot\&. If your chroot target is not a mountpoint, you can bind mount the directory on itself to make it a mountpoint, i\&.e\&.:
.sp
\fImount \-\-bind /your/chroot /your/chroot\fR
.sp .5v

.SH "OPTIONS"
.PP
\fB\-S\fR
.RS 4
Run in systemd mode\&. This will spawn a transient systemd service via
\fBsystemd-run\fR(1)
and delegates namespace/chroot management to the service manager\&.
.RE
.PP
\fB\-N\fR
.RS 4
Run in unshare mode\&. This will use
\fBunshare\fR(1)
to create a new mount and user namespace, allowing regular users to create new system installations\&.
.RE
.PP
\fB\-u <user>[:group]\fR
.RS 4
Specify non\-root user and optional group to use\&.
.RE
.PP
\fB\-r\fR
.RS 4
Do not change the resolv\&.conf within the chroot\&. This means that the resolver might not work in the chroot, which could be the required state\&.
.RE
.PP
\fB\-h\fR
.RS 4
Output syntax and command line options\&.
