The FHS recommends that we use /var/lib/hwclock, instead of the usual /etc, as the location of the adjtime file. To make hwclock FHS-compliant, run the following: cp hwclock/hwclock.c{,.backup} sed 's%etc/adjtime%var/lib/hwclock/adjtime%' \     hwclock/hwclock.c.backup > hwclock/hwclock.c mkdir -p /var/lib/hwclock Prepare Util-linux to be compiled: ./configure Continue with compiling the package: make HAVE_SLN=yes The HAVE_SLN option prevents this package, which was already was installed by Glibc, from being built again. Finish installing the package: make HAVE_SLN=yes install
