MongoDB tries to use user _mongo, which does not exist

[inDigiNeous (Sakari Lehtonen)]

After updating to Os X Mavericks 10.9.1, mongodb no longer launches, instead I get this error message in console:

28.1.2014 15.29.26,050 sudo[25708]:     root : TTY=unknown ; PWD=/ ; USER=_mongo ; COMMAND=/opt/local/bin/mongod --dbpath /opt/local/var/db/mongodb --logpath /opt/local/var/log/mongodb/mongodb.log --logappend
28.1.2014 15.29.26,096 com.apple.launchd[1]: (org.macports.mongodb) Throttling respawn: Will start in 10 seconds

Seems that it is trying to launch as use '_mongo'.

My Mac Os X system does not have this user.

In the future, please use WikiFormatting and Cc the port maintainers (port info --maintainers mongodb).

I think it's probably solved. I installed mongodb on 10.9.2 and it runs fine. Portfile has _mongo user with add_users. So should be fine. probably want to use launchctl to start/stop daemon

Nothing has changed in the port with regard to the way the users are set up in a long time.

To the original reporter: you mentioned having upgraded to Mavericks. The scenario you describe sounds like you may not have uninstalled and reinstalled MacPorts and all ports after doing so. See wiki:Migration.
