11. Create the image. In the case of a boot images, the kernel used to create
this boot image is additionally extracted. All other images are fitted with
a checksum file (Imagename.md5). The checksum file contains the md5
sum and the size of the image file in bytes.
This standard procedure may be affected by the following functions:
Prepare image only (prepare). In this case, only the system tree is gen-
erated, without a file system image being created from it. This structure
can then be manually modified.
Directly create image (build). In this case, it is assumed that there is
already an existing system tree from which the file system image can be
generated.
Insert image extension (extend). In this case, a file can be indicated in
the format of the setup file, which can include the following specifica-
tions:
– Package description
Package description defines a line in the format of the setup file
that indicates what the package is called, which RPM options must
be used to install it, which version of the package should be used,
and in which directory the package is located. If no directory is
indicated, the system will search for the package in the package
directory corresponding to that image.
– config
Following the optional keyword config, the name of an RPM, which
contains special configuration files, provided by SUSE appears. The
package is then unpacked into the files-user directory with cpio.
Image with password protection (feature=auth). In this case, the system
requests a password for the root user during the generation of the file
system image. The encrypted password is then entered in the existing
/etc/shadow.
Image with serial console support (feature=serial_console). In this case,
the corresponding files inittab and securetty are generated and stored
in the files-user tree.
Image with alias name (feature=set_alias). In this case, the variable
NAME within the appropriate linuxrc script is changed, which causes
the boot process of the cash register to stop and ask for an alias name.
Allowed values for this feature are the following:
– Value [n] greater than zero
The question for the alias name appears, but the user is forced to
enter a name within [n] seconds.
