Usual options for udev installed in the root filesystem are:
./configure \
--prefix=/usr \
--sysconfdir=/etc \
--sbindir=/sbin \
--libdir=/usr/lib64 \
--with-rootlibdir=/lib64 \
--libexecdir=/lib/udev \
--with-selinux
All options:
--prefix=
Usually /usr, prefix for man pages, include files.
--sysconfdir=
Usually /etc.
--sbindir=
Usually /sbin, the place for udevd and udevadm.
--libexecdir=
Usually /lib/udev, the udev private directory.
--enable-debug
Compile-in verbose debug messages. Usually not needed,
it increases the size of the binaries.
--disable-logging
Disable all logging and compile-out all log strings. This
is not recommended, as it makes it almost impossible to debug
udev in the running system.
--with-selinux
Link against SELinux libraries to set the expected context
for created files.
--disable-extras
Disable the build of all extras which have larger external
dependencies like glib, libacl, libusb, ...
The options used in a RPM spec file usually look like:
%configure \
--prefix=%{_prefix} \
--sysconfdir=%{_sysconfdir} \
--sbindir=%{_sbindir} \
--libdir=%{_libdir} \
--with-rootlibdir=/%{_lib} \
--libexecdir=/lib/udev \
--with-selinux
The defined location for scripts and binaries which are called
from rules is /lib/udev/ on all systems and architectures. Any
other location will break other packages, who rightfully expect
the /lib/udev/ directory, to install their rule helper and udev
rule files.
It is recommended to use the /lib/udev/devices/ directory to place
device nodes, directories and symlinks, which are copied to /dev/
at every bootup. That way, nodes for devices which can not be
detected automatically, or are activated on-demand by opening the
pre-existing device node, will be available.
Default udev rules and persistent device naming rules are required
by other software that depends on the data udev collects from the
devices, and should therefore be installed by default with every udev
installation.
