[pkg-fetchmail-maint] Bug#699425: Fetchmail's resolvconf update script can be simplified

[Thomas Hood]

Package: fetchmail
Version: 6.3.22-2
Severity: minor

Fetchmail's resolvconf update script
(/etc/resolvconf/update-libc.d/fetchmail) can be simplified.

Resolvconf no longer calls update scripts with "--nscd" to indicate that
nscd is running and has been restarted. (Resolvconf no longer restarts nscd
when resolv.conf changes.) Consequently, the while...done statement can be
deleted from fetchmail's resolvconf update script as shown in the appended
patch.

Whether or not it is still necessary to "awaken" fetchmail after a
resolv.conf change, I don't know. Someone who knows fetchmail better than I
do will have to be the judge of that. They just need to be aware that the
glibc resolver has been enhanced such that resolver clients are asked to
re-initialize the resolver when resolv.conf changes. At least for nscd that
means that nscd doesn't have to be restarted after a resolv.conf change (as
it once did have to be).
