This command invokes the following targets: +- `install-bin` +- `install-man` +- `install-udev` + +After installing mdadm, consider rebuilding initramfs to ensure the changes take effect. + +List of installation targets: +- Run `make install-bin` to install the mdadm and mdmon binary files. +- Run `make install-systemd` to install the systemd services. +- Run `make install-udev` to install the udev rules. +- Run `make install-man` to install the manual pages (`mdadm.8`, `md.4`, `mdadm.conf.5`, +`mdmon.8`). + +The following targets are deprecated and should not be used: +- `install-static` +- `install-tcc` +- `install-uclibc` +- `install-klibc` + # License It is released under the terms of the **GNU General Public License version 2** as published |
