The

Apply changes in the

\fIPREFIX_DIR\fR
|

directory and use the configuration files from the
|

\fIPREFIX_DIR\fR

directory\&. This option does not chroot and is intended for preparing a cross\-compilation target\&. Some limitations: NIS and LDAP users/groups are not verified\&. PAM authentication is using the host files\&. No SELINUX support\&.

.RE

The default behavior (if the

options are not specified) is defined by the

The following configuration variables in

change the behavior of this tool:
|
||
.PP
|
||
\fBMAX_MEMBERS_PER_GROUP\fR (number)
|
||
.RS 4
|
||
Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
|
||
/etc/group
|
||
(with the same name, same password, and same GID)\&.
|
||
.sp
|
||
The default value is 0, meaning that there are no limits in the number of members in a group\&.
|
||
.sp
|
||
This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.
|
||
.sp
|
||
If you need to enforce such limit, you can use 25\&.
|

.sp

Note: split groups may not be supported by all tools (even in the Shadow toolsuite)\&. You should not use this variable unless you really need it\&.
