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 on the running system.
--with-selinux
Link against SELinux libraries to set the expected context
for created files.
--disable-rule_generator
Disable persistent network, cdrom naming support.
--disable-hwdb
Disable hardware database support
--disable-udev_acl
Disable local user acl permissions support.
--disable-gudev
Disable Gobject libudev support.
--disable-introspection
Disable Gobject introspection support.
--disable-keymap
Disable keymap fixup support.
--enable-floppy
Enable legacy floppy support.
--enable-edd
Enable disk edd support.
The options used in a RPM spec file usually look like:
%configure \
--prefix=%{_prefix} \
--sysconfdir=%{_sysconfdir} \
--sbindir=/sbin \
--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 possible 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 may be required
by other software that depends on the data udev collects from the
devices.
