Subject: dhclient - Try harder to re-initialize parsing state.
X-Git-Tag: v3.2.0~324
X-Git-Url: https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff_plain/8bd3111e4cda790603d42ecc5505a5c6a6c42d48?ds=sidebyside

dhclient - Try harder to re-initialize parsing state.

- Attempt that nothing accidentally carries over when
  a new file (i.e. leases after config) is parsed.
  May help with mysterious "Corrupt lease file" messages.
