NAMESPACE(6) Games Manual NAMESPACE(6)
NAME
namespace - name space description file
DESCRIPTION
Namespace files describe how to construct a name space from scratch, an operation normally performed by the newns subroutine (see auth(2))
which is typically called by init(8). Each line specifies one name space operation. Spaces and tabs separate arguments to operations; no
quotes or escapes are recognized. Blank lines and lines with # as the first non-space character are ignored. Environment variables of the
form $name are expanded within arguments, where name is a UTF string terminated by white space, a /, or a $.
The known operations and their arguments are:
mount [-abc] servename old [spec]
Mount servename on old.
bind [-abc] new old
Bind new on old.
import [-abc] host "[remotepath]mountpoint
Import remotepath from machine server and attach it to mountpoint.
cd dir Change the working directory to dir.
The options for bind, mount, and import are interpreted as in bind(1) and import(4).
