# Apply patches:

# configure accepts --libdir, but the scripts still need to be edited
# or they won't work:
sed -i "s|/usr/lib/dracut|/usr/lib$LIBDIRSUFFIX/dracut|g" *.sh

# Configure:
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
./configure \
   --prefix=/usr \
   --libdir=/usr/lib${LIBDIRSUFFIX} \
   --sysconfdir=/etc \

# Build:
make $NUMJOBS || make || failmake

# Install into package framework:
make install DESTDIR=$PKG || failinstall

# Include elogind-uaccess-command to allow processing uaccess rules correctly:
cat $CWD/elogind.conf | sed "s#/lib/#/lib${LIBDIRSUFFIX}/#g" > $PKG/etc/dracut.conf.d/elogind.conf.new

# Don't search for systemd services in the startup messages --
# it's scaring the children. ;-)
cat $CWD/omit_systemd_modules.conf > $PKG/etc/dracut.conf.d/omit_systemd_modules.conf.new

# Set hostonly_cmdline=yes, otherwise encrypted root will fail.
echo "hostonly_cmdline=yes" > $PKG/etc/dracut.conf.d/hostonly_cmdline_yes.conf.new

# Set i18n_vars to prevent a warning:
