System: NetBSD beta 4.0_BETA2 NetBSD 4.0_BETA2 (164LX) #1: Wed Feb 28 23:26:44 CET 2007 pavel@beta:/mnt/obj/alpha-4/164LX alpha
Architecture: alpha
Machine: alpha
>Description:
Upgrade to NetBSD 4.0_BETA2 removes sendmail configuration in
/etc/mail and /usr/share/sendmail. If one configures sendmail by
editing the default netbsd-proto.mc instead of copying and modifying
it, one would lose the configuration. 

Removal of files in /etc is conditional on not having the sendmail
package, which is insufficient. One could e.g. have a manually
compiled sendmail in /usr/local or want to install the package after
upgrading to NetBSD 4, not before.

N.B. postinstall, which does both actions, is run automatically from
sysinst.
>How-To-Repeat:
Upgrade from NetBSD 3.x to 4.0 using sysinst.
>Fix:
do not mark /usr/share/sendmail/* as obsolete. Remove the postinstall
sendmail "fix" or at least make it non-default.
