Systemd/src/udev/INSTALL

The options used usually look like:
  %configure \
    --prefix=/usr \
    --sysconfdir=/etc \
    --bindir=/usr/bin \
    --libdir=/usr/lib64 \
    --libexecdir=/usr/lib \
    --with-systemdsystemunitdir=/usr/lib/systemd/system \
    --with-selinux

The options used in a RPM spec file look like:
  %configure \
    --prefix=%{_prefix} \
    --sysconfdir=%{_sysconfdir} \
    --bindir=%{_bindir} \
    --libdir=%{_libdir} \
    --libexecdir=%{_prefix}/lib \
    --with-systemdsystemunitdir=%{_prefix}/lib/systemd/system \
    --with-selinux

The options to install udev in the rootfs instead of /usr,
and udevadm in /sbin:
    --prefix=%{_prefix} \
    --with-rootprefix= \
    --sysconfdir=%{_sysconfdir} \
    --bindir=/sbin \
    --libdir=%{_libdir} \
    --with-rootlibdir=/lib64 \
    --libexecdir=/lib \
    --with-systemdsystemunitdir=/lib/systemd/system \
    --with-selinux

Some tools expect udevadm in 'sbin'. A symlink to udevadm in 'bin'
needs to be manually created if needed.

The defined location for scripts and binaries which are called
from rules is (/usr)/lib/udev/ on all systems and architectures. Any
other location will break other packages, who rightfully expect
the (/usr)/lib/udev/ directory, to install their rule helper and udev
rule files.

Default udev rules and persistent device naming rules may be required
by other software that depends on the data udev collects from the
devices.
