Hide Forgot
(sorry if this is a repeat; I thought I saw a similar bug during beta1, but now I can't find the bug number). During install, I selected postfix. I meant to deselect sendmail, but must have overlooked it when wading through the individual package list.... After reboot, both postfix and sendmail were on the box, and both were running (a setup which just plain Doesn't Work). I'm not sure if this should be fixed in anaconda, or in the respective sendmail and postfix .SPEC files, but those two packages need to conflict with each other, and should not be simultaneously installed.
They don't conflict and should be able to be simultaneously installed, but their alternatives magic isn't quite right yet. Assigning to Bill and moving to chkconfig since that's where the alternatives stuff is and I know Bill was working on some things related to this last night
Ah, so the idea will be that chkconfig magically takes care of /etc/alternative symlinks whenever switching between MTAs? At any rate, here's exactly what I saw after install. postfix processes were running (nqmgr, master, etc.), and sendmail -q1h -mumble was also running.... At that point, when I tried sending mail, it died a horrible and painful death trying to connect to an SMTP server (which I didn't find too surprising, given that both MTAs were running ;-). However, both sendmail and postfix rpms are buggy (postfix just doesn't work out of the box currently, since the chroot is messed up, and sendmail's modifications of /etc/alternatives appear to be buggy, judging by the errors I got when I tried to uninstall it), so I'm not sure if mail not working was due to dueling mtas, or to the fact that neither mta currently works w/o modification.... I'll try to do another install later today and get more info.
Correct; starting with chkconfig-1.3.0, alternatives takes a --initscript option; it then handles disabling/enabling whichever ones it needs to. Of course, this isn't in the beta. Marking resolved in rawhide; other issues with the MTAs not actually working may still be a problem.
