Re: [libvirt] [PATCH] build: add $(prefix) to SYSTEMD_UNIT_DIR

I noticed this problem when adding systemd support to netcf, because I setup the configure.ac to automatically prefer using systemd over initscripts when possible - although I had copied the install-data-local target from the example of libvirt's "libvirt-guests" service more or less verbatim, "make distcheck" would fail because it was trying to install the service file directly into /lib/systemd/system rather than into /home/user/some/unimportant/name/lib/systemd/system. This is caused by the install/uninstall rules for the systemd unit files relying on $(DESTDIR) pointing the installed files to the right place, but in reality $(DESTDIR) is empty during this part of make distcheck - it instead sets $(prefix) with the toplevel directory used for its test build/install/uninstall cycle. (This problem hasn't been seen when running "make distcheck" in libvirt because libvirt will never build/install systemd support unless explicitly told to do so on the configure commandline, and "make distcheck" doesn't put the "--with-initscript=..." option on the configure commandline.)

I verified that the same problem does exist in libvirt by modifying libvirt's configure.ac to set: init_systemd=yes with_init_script=systemd+redhat This forces a build/install of the systemd unit files during distcheck, which yields an error like this: /usr/bin/install -c -m 644 virtlockd.service \ /lib/systemd/system/ libtool: install: warning: relinking `libvirt-qemu.la' /usr/bin/install: cannot remove '/lib/systemd/system/virtlockd.service': Permission denied make[4]: *** [install-systemd] Error 1 After adding $(prefix) to all the definitions of SYSTEMD_UNIT_DIR, make distcheck now completes successfully with the modified configure.ac, and the above lines change to something like this: /usr/bin/install -c -m 644 virtlockd.service \ /home/laine/devel/libvirt/libvirt-1.2.1/_inst/lib/systemd/system/
