Bash shell). If no machine is speciﬁed here, any machine is allowed to im-

port this ﬁle system with the given permissions.

Set permissions for the ﬁle system to export in brackets after the machine

name. The most important options are:

Table 21.12: Permissions for Exported File System

option meaning

ro File system is exported with read-only permission

(default).

rw File system is exported with read-write

permission.

root_squash This makes sure the user root of the given ma-

chine does not have root permissions on this

ﬁle system. This is achieved by assigning user ID

65534 to users with user ID 0 (root). This user

ID should be set to nobody (which is the default).

no_root_squash Does not assign user ID 0 to user ID 65534, keep-

ing the root permissions valid.

link_relative Converts absolute links (those beginning with /)

to a sequence of ../. This is only useful if the en-

tire ﬁle system of a machine is mounted (default).

link_absolute Symbolic links remain untouched.

map_identity User IDs are exactly the same on both client and

server (default).

map_daemon Client and server do not have matching user IDs.

This tells nfsd to create a conversion table for user

IDs. The ugidd daemon is required for this to

work.
