고려할 사항 ¶
Debian has three separate places where software is installed, corresponding to the three different ways of installing software: /usr contains software managed by the APT system and installed by root; /usr/local contains non-APT software installed by root; and each user's home directory contains user-installed software. This is rather confusing for everyone, and leads to duplication if several users install the same software in their home directories.
서버 클라이언트 ¶
Automatically downloading and running programs across the Internet can sound like a virus-builder’s dream. ActiveX especially brings up the thorny issue of security in client-side programming. If you click on a Web site, you might automatically download any number of things along with the HTML page: GIF files, script code, compiled Java code, and ActiveX components. Some of these are benign; GIF files can’t do any harm, and scripting languages are generally limited in what they can do. Java was also designed to run its applets within a “sandbox” of safety, which prevents it from writing to disk or accessing memory outside the sandbox. ActiveX is at the opposite end of the spectrum. Programming with ActiveX is like programming Windows – you can do anything you want. So if you click on a page that downloads an ActiveX component, that component might cause damage to the files on your disk. Of course, programs that you load onto your computer that are not restricted to running inside a Web browser can do the same thing. Viruses downloaded from Bulletin-Board Systems (BBSs) have long been a problem, but the speed of the Internet amplifies the difficulty. The solution seems to be “digital signatures,” whereby code is verified to show who the author is. This is based on the idea that a virus works because its creator can be anonymous, so if you remove the anonymity individuals will be forced to be responsible for their actions. This seems like a good plan because it allows programs to be much more functional, and I suspect it will eliminate malicious mischief. If, however, a program has an unintentional bug that’s destructive it will still cause problems. 프로그램의 구분 ¶

syscoca ¶Sycoca stands for System Configuration Cache and is nominated to be the succesor of kregistry. It is a light weight database optimized for looking up static system configuration information fast and with minimal memory usage.
The database will offer read-only access to many clients at once. The database is read-only which means that looking up can be very fast since no locking or transaction operations need to be performed. The database is created/updated by kbuildsycoca from human readable configuration files. kded monitors these configuration files and will call kbuildsycoca to update the database when a change in any of the configuration files is detected.
Updating the database will mean that the database is replaced as a whole by a more up to date version. This approach allows a very straight forward database implementation. With Sycoca it will not be necessary any more to parse multiple files when looking for static system information. Instead Sycoca can return the requested information with a performance near to O(1). Examples of static system information are mimetype bindings and .desktop information (servicetypes). Application specific configuration information will _NOT_ be stored in Sycoca since this information is usually subject to regular change.
KDE Daemon - triggers Sycoca database updates when needed.

20.How to check the RPM dependency
When making custom-made CD etc.,which is necessary to investigate the dependency of the RPM files.
It can investigate easily as follows:
Premise:The directory with RPM files are /tmp/i386/RedHat/RPMS
$cd /tmp/i386/RedHat/RPMS
Make the directory for test
$mkdir -p /tmp/testdb
Initialize the RPMDB
$rpm --initdb --dbpath /tmp/testdb
Dependency check
$rpm --test --dbpath /tmp/testdb -Uvh *.rpm
The message will be outputted if caught in the check of the dependency, Please add the required RPM files.

unionfs ¶디자인 자체가 달라져야 할 것 같다.
부여의 경우 root 와 일반유저의 구분이 있으므로, klik 나 zero install 을 사용할 필요가 없을 것 같다.
오히려 java 를 이용하는 것이 낳지 않을까?
java 가 할 수 없는 일이 어떤 것들인가?
