Ketika meng-install sebuah package sudah biasa kita harus meng-install juga package-package yang dibutuhkan (dependensi). Namun, ketika kita hendak menghapus (uninstall) package tersebut, package-package dependensinya tidak ikut terhapus. Jadi, terasa mubazir, package-package dependensi tersebut tidak terpakai.
Misalnya, kita install package kdeedu-kstars:
[hafni@localhost ~]$ su -c 'yum install kdeedu-kstars' Password: Loaded plugins: fastestmirror, refresh-packagekit Loading mirror speeds from cached hostfile * rpmfusion-nonfree-updates: astromirror.uchicago.edu * rpmfusion-free-updates: astromirror.uchicago.edu * rpmfusion-free: astromirror.uchicago.edu * rpmfusion-nonfree: astromirror.uchicago.edu Setting up Install Process Parsing package install arguments Resolving Dependencies --> Running transaction check ---> Package kdeedu-kstars.x86_64 0:4.2.1-1.fc10 set to be updated --> Processing Dependency: kdeedu-libs = 4.2.1-1.fc10 for package: kdeedu-kstars --> Processing Dependency: libindi.so.0()(64bit) for package: kdeedu-kstars --> Processing Dependency: libkdeeduui.so.4()(64bit) for package: kdeedu-kstars --> Processing Dependency: libcfitsio.so.0()(64bit) for package: kdeedu-kstars --> Running transaction check ---> Package cfitsio.x86_64 0:3.100-1.fc10 set to be updated ---> Package kdeedu-libs.x86_64 0:4.2.1-1.fc10 set to be updated ---> Package libindi.x86_64 0:0.6-4.fc10 set to be updated --> Processing Dependency: libfli.so.1()(64bit) for package: libindi --> Processing Dependency: libnova-0.12.so.1()(64bit) for package: libindi --> Running transaction check ---> Package libfli.x86_64 0:1.7-4.fc10 set to be updated ---> Package libnova.x86_64 0:0.12.1-3.fc10 set to be updated --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: kdeedu-kstars x86_64 4.2.1-1.fc10 fedora-updates-handmade 10 M Installing for dependencies: cfitsio x86_64 3.100-1.fc10 fedora-handmade 1.3 M kdeedu-libs x86_64 4.2.1-1.fc10 fedora-updates-handmade 345 k libfli x86_64 1.7-4.fc10 fedora-updates-handmade 38 k libindi x86_64 0.6-4.fc10 fedora-updates-handmade 700 k libnova x86_64 0.12.1-3.fc10 fedora-handmade 1.1 M Transaction Summary ================================================================================ Install 6 Package(s) Update 0 Package(s) Remove 0 Package(s) Total download size: 14 M Is this ok [y/N]: y Downloading Packages: (1/6): libfli-1.7-4.fc10.x86_64.rpm | 38 kB 00:00 (2/6): kdeedu-libs-4.2.1-1.fc10.x86_64.rpm | 345 kB 00:00 (3/6): libindi-0.6-4.fc10.x86_64.rpm | 700 kB 00:00 (4/6): libnova-0.12.1-3.fc10.x86_64.rpm | 1.1 MB 00:00 (5/6): cfitsio-3.100-1.fc10.x86_64.rpm | 1.3 MB 00:00 (6/6): kdeedu-kstars-4.2.1-1.fc10.x86_64.rpm | 10 MB 00:01 ------------------------------------------------------------------------------------- Total 4.2 MB/s | 14 MB 00:03 Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Installing : cfitsio 1/6 Installing : libfli 2/6 Installing : kdeedu-libs 3/6 Installing : libnova 4/6 Installing : libindi 5/6 Installing : kdeedu-kstars 6/6 Installed: kdeedu-kstars.x86_64 0:4.2.1-1.fc10 Dependency Installed: cfitsio.x86_64 0:3.100-1.fc10 kdeedu-libs.x86_64 0:4.2.1-1.fc10 libfli.x86_64 0:1.7-4.fc10 libindi.x86_64 0:0.6-4.fc10 libnova.x86_64 0:0.12.1-3.fc10 Complete!
Dari meng-install kdeedu-kstars tersebut, kita harus meng-install 5 package lain, yaitu cfitsio, libfli, kdeedu-libs, libnova, dan libindi. Nah, ketika hendak menghapus package kdeedu-kstars, 5 package ini tidak ikut terhapus. Berikut ini buktinya:
[hafni@localhost ~]$ su -c 'yum remove kdeedu-kstars' Password: Loaded plugins: fastestmirror, refresh-packagekit Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package kdeedu-kstars.x86_64 0:4.2.1-1.fc10 set to be erased --> Finished Dependency Resolution Dependencies Resolved ======================================================================================= Package Arch Version Repository Size ======================================================================================= Removing: kdeedu-kstars x86_64 4.2.1-1.fc10 installed 21 M Transaction Summary ======================================================================================= Install 0 Package(s) Update 0 Package(s) Remove 1 Package(s) Is this ok [y/N]: N Exiting on user Command Complete!
Cara tergampang untuk turut serta menghapus package dependensinya, kita install salah satu plugin yum yang berguna untuk menghapusnya, yaitu yum-remove-with-leaves. Silakan install dulu:
[hafni@localhost ~]$ su -c 'yum install yum-remove-with-leaves'
Nah, setelah kita meng-install plugin tersebut, kita coba hapus package kdeedu-kstars:
[hafni@localhost ~]$ su -c 'yum remove kdeedu-kstars' Password: Loaded plugins: fastestmirror, refresh-packagekit, remove-with-leaves Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package kdeedu-kstars.x86_64 0:4.2.1-1.fc10 set to be erased --> Finished Dependency Resolution removing kdeedu-libs-4.2.1-1.fc10.x86_64.

Dengan plugin yum-remove-with-leaves, package-package dependensi jadi ikut terhapus. Sekarang tidak ada lagi package yang tidak terpakai.
