I don't recall if this has come up before, but I suggest a couple of
changes to the default util-linux build configuuration:
1. Change the default ADJTIME_PATH to be /var/lib/hwclock/adjtime
This would be a one line change to include/pathnames.h:
# define _PATH_ADJTIME "/etc/adjtime"
For a reference, see the FHS paragraph 5.8.6:
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s08.html#varlibhwclockStateDirectoryForHwclo
Currently this behavior can be done by exporting the environment
variable ADJTIME_PATH=/var/lib/hwclock/adjtime before running configure,
but is undocumented except in the 2.25 release notes.
2. Change the references to /var/run to just /run or at least add a
configure option --runstatedir=<path>.
Most systems today create /run as a tmpfs. See:
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s15.html and
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s13.html
Currently this change can be manually made by setting an environment
variable, runstatedir=/run when running configure, but is undocumented.
