The FHS recommends that we use /var/lib/hwclock as the location of the adjtime file, instead of the usual /etc. To make hwclock, which is part of the util-linux package, FHS-compliant, run the following. sed 's|etc/adjtime|var/lib/hwclock/adjtime|' \    hwclock/hwclock.c > hwclock~ && mv hwclock~ hwclock/hwclock.c && mkdir /var/lib/hwclock Install Util-Linux by running the following commands: ./configure && make HAVE_SLN=yes ADD_RAW=yes && make HAVE_SLN=yes ADD_RAW=yes install
