I. RCS definitionany electromagnetic waves with a definite polarization are exposed to the target, which can cause refraction or scattering in all directions. The scattering wave is divided into two parts: one is composed of the scattering wave with the same polarization as the receiving antenna, and the two is the different change of the scattering wave, and the receiving antenna is not responding. These two polarization orthogonal, respectively call
The following describes how to ensure the security of server configuration files-Linux Enterprise applications-Linux server applications. Have you ever been overwhelmed by server faults caused by configuration file changes? Have you ever gotten rid of a server suddenly, but you still cannot remember what kind of virus you had on the configuration file a few weeks ago? Have you ever wondered which administrator's configuration has caused a server fault? Are you afraid of Server failure and dare n

This problem has plagued me for a long time. Many people on the Internet also have this problem, but it seems that most people have not been able to solve it.
Finally, I decided to find the answer in the English forum, and solved the problem of failure in reading the RCS file when busybo was started.
Because the RFM file is edited in
Programme: hi3518c+imx225;
Problem:
To annotate the process script, modify it to MPP debugging, and the annotation process cannot be wq. Write save, can only go to Q. Forced exit;

After kernel mount the root file system, the first program to run is the LINUXRC under the root directory, which is actually a link to/bin/busybox, which means that the first program to run after the system is busybox itself.
BusyBox first resolves the/etc/inittab configuration file, which reads as follows:
# Boot-time System configuration/initialization script.

With the help of the startup script, you can set up a variety of programs to run automatically after boot, or you can set other system settings, which is
Similar to the Autobat automatic batch file in Windows system, the startup script is located in the/etc/init.d/rcs of the board

This article is "Daily build [4]: related tools.Because the source code version control system (RvS) is a "Daily build process ",This is the first step, so when I am introducing the related tools built on a daily basis, I will first talk about the software of the RCS class.
★Old school's RCSThroughout the entire software development lifecycle, the RCS is at a very basic position. Many software engineering
incorporated the original rootfs into initrd so that it can act as rootfs directly to save the startup time and reduce the volume. (This transformation scheme is relatively simple and sufficient to meet actual needs)
The transformation process is mainly based on the initrd image automatically generated by the original make install, the following "operation" is performed ":
(1) Replace the initialization script in the original initrd with the busrc
1. What is SVN? SVN is the abbreviation for Subversion, is an open source version control system, compared to RCS, CVS, it uses the branch management system, its design goal is to replace CVS. Many version control services on the Internet have migrated from CVs to subversion.centralized management of workflows such as:the core of centralized code management is the server, where all developers have to get the code from the server before starting a new
! + ----- ++ In fact, Most CVs users do not need to consider the revision number; they only need to know that CVS has automatically added revision numbers like 1.1 and 1.2. 1.2 tag because each file has its own revision number, each time it is submitted, its revision number will be increased. In this case, a problem occurs: for a software release, the revision numbers of the source files may be different. Example: Ci. c 5.21 Co. c 5.9 ident. c 5.3 RCS
directory to edit files, it is a good idea to delete the original code. Of course, it is wise to keep a backup to another place before you delete it. The "checkout" command can use the module name as a parameter (as in all previous examples) or a path relative to $ cvsroot, as shown in the preceding example. You should check whether the permissions in the CVS directory are appropriate and make them belong to a specific group. See section 2.2.2 [file permissions]. If you want to "import" some fi
