Title:
  /sbin/dhclient-script causes insufficient feedback "/sbin/dhclient-
  script: 28: .: Can't open /usr/share/sendmail/dynamic"

Status in isc-dhcp package in Ubuntu:
  Expired

Bug description:
  Since `/sbin/dhclient-script` is a bash script it's very hard to trace
  back the error/figure out what actually happened because `bash` can't
  provide information about exceptional states (line 28 is just the
  error logging function).

  I'd be appreciated if the script was ported to Python because it
  provides state-of-the-art scripting facilities.

  I encounter this situation during `sudo systemctl restart
  networking.service`.
