8 <para>The server will <command moreinfo="none">chroot()</command> (i.e.
9 Change its root directory) to this directory on startup. This is
10 not strictly necessary for secure operation. Even without it the
11 server will deny access to files not in one of the service entries.
12 It may also check for, and deny access to, soft links to other
13 parts of the filesystem, or attempts to use ".." in file names
14 to access other directories (depending on the setting of the
15 <smbconfoption name="wide smbconfoptions"/> parameter).
18 <para>Adding a <parameter moreinfo="none">root directory</parameter> entry other
19 than "/" adds an extra level of security, but at a price. It
20 absolutely ensures that no access is given to files not in the
21 sub-tree specified in the <parameter moreinfo="none">root directory</parameter>
22 option, <emphasis>including</emphasis> some files needed for
23 complete operation of the server. To maintain full operability
24 of the server you will need to mirror some system files
25 into the <parameter moreinfo="none">root directory</parameter> tree. In particular
26 you will need to mirror <filename moreinfo="none">/etc/passwd</filename> (or a
27 subset of it), and any binaries or configuration files needed for
28 printing (if required). The set of files that must be mirrored is
29 operating system dependent.</para>
