## Installing CRIU from source code
Once CRIU is built one can easily setup the complete CRIU package
(which includes executable itself, CRIT tool, libraries, manual
and etc) simply typing
make install
this command accepts the following variables:
* **DESTDIR**, to specify global root where all components will be placed under (`/` by default);
* **PREFIX**, to specify additional prefix for path of every component installed (`/usr/local` by default);
* **BINDIR**, to specify where to put CRIT tool (`$(PREFIX)/bin` by default);
* **SBINDIR**, to specify where to put CRIU executable (`$(PREFIX)/sbin` by default);
* **MANDIR**, to specify directory for manual pages (`$(PREFIX)/share/man` by default);
* **SYSTEMDUNITDIR**, to specify place where systemd units are living (`$(PREFIX)/lib/systemd/system` by default);
* **LIBDIR**, to specify directory where to put libraries (`$(PREFIX)/lib` by default).
Thus one can type
make DESTDIR=/some/new/place install
and get everything installed under `/some/new/place`.
## Uninstalling CRIU
To clean up previously installed CRIU instance one can type
make uninstall
and everything should be removed. Note though that if some variable (**DESTDIR**, **BINDIR**
and such) has been used during installation procedure, the same *must* be passed with
uninstall action.
