dnl This section should include only the definition of configure script

dnl possible, other than what's needed to determine values and defaults.
dnl Per the autoconf docs, --enable-*/--disable-* options should control
dnl features inherent to Pacemaker, while --with-*/--without-* options should
dnl control the use of external software. However, --enable-*/--disable-* may
dnl implicitly require additional external dependencies, and
dnl --with-*/--without-* may implicitly enable or disable features, so the
dnl line is blurry.

dnl We also use --with-* options for custom file, directory, and path

# Fedora >=42 makes /usr/sbin a symlink to /usr/bin. It updates the RPM macros
# to set _sbindir to "${_exec_prefix}/bin", the same value as _bindir.
# Previously it was set to "${_exec_prefix}/sbin". (Note that because of the
# symlink, paths beginning with /usr/sbin remain valid.)
#
# This causes problems with bundle resources. Pacemaker automatically generates
# a configuration for the bundle's container resource. If the bundle contains a
# primitive and the container's run-command attribute is unset, the generated
# container resource has its run_cmd attribute set to
# SBIN_DIR "/" PCMK__SERVER_REMOTED, which is intended as a reasonable default.
# If SBIN_DIR becomes "/usr/bin" instead of "/usr/sbin", at least two problems
# can occur:
# 1. The container resource's digest changes compared to the digest in the
# resource history entry. Pacemaker interprets this as a configuration
# change and restarts the container resource.
# 2. If the container is running a different OS distro or an older version of
# Fedora, then the new /usr/bin/pacemaker-remoted path may be invalid; the
# executable was installed at /usr/sbin/pacemaker-remoted, which is NOT a
# symlink to /usr/bin path. In this case, the container fails to start.
#
# We override the value only for the SBIN_DIR constant, which is used only for
# the sbd path and the default pacemaker-remoted path. There is no need to
# override sbindir, which would affect installation directories.
#
# There is no more specific way than the below, to detect whether the build
# system has this /usr/sbin vs. /usr/bin change in effect. Thus corner cases are
# possible when sbindir/bindir are manually specified or in distros with
# atypical defaults.
#
# At time of writing, autoconf is unchanged. However, we perform the override
# here instead of in the spec file, in case autoconf changes in the future.
#
# Note that other distros (for example, RHEL) are likely to incorporate these
# changes in the future.
