An installation program or installer is a computer program that installs files, such as applications, drivers, or other software, onto a computer.
Some installers are specifically made to install the files they contain; other installers are general-purpose and work by reading the contents of the software package to be installed.
- Is an installer always used for binary installation and not doing any compilation work for source installation?
- Does Linux have the concept "installer" for package installation?
Wikipedia distinguishes between "installer" and "Package management
system". In Ubuntu, it seems to me all binary installation is done
by Package management systems
apt- so where is an "installer"?
