Must set 'daemonUser in Linux' if daemonUser != name

[hfs]

I use sbt-native-packager to package a Play 2.2 application as .deb for Ubuntu with Upstart. The server stuff in 0.7 is great and I’m already using it. You are solving my problems faster than I could even report them (support for daemonGroup, #178). Awesome work!

I noticed a little thing with 0.7.0-RC1: In my application name is different than daemonUser, and daemonGroup is again different from that. When I only have

daemonUser := 'daemonUser'

in build.sbt, the (empty) directories /var/log/appname and /var/run/appname are owned by appname:daemonGroup instead of daemonUser:daemonGroup. This leads to an additional, unwanted user appname to be created in the postinstall script.

If instead I put both

daemonUser := 'daemonUser'

daemonUser in Linux := 'daemonUser'

in build.sbt, everything to be owned by the process’ user is owned by daemonUser:daemonGroup as expected.

So, a workaround is available, but it would be nicer if only daemonUser had to be set.

Thanks :) This is just a config issue. You have to scope the daemonUser.

daemonUser in Linux := "daemon-user"

daemonGroup in Linux := "daemon-group"

Aha! I had an unscoped reference to daemonUser elsewhere in build.sbt and didn’t read the error messages properly… Thanks for your help!

Nevermind. Thinking a bit more on this, I'm not sure if the Linux scope is correct here. @jsuereth , @aparkinson would it be better to keep the references of daemonUser and daemonGroup unscoped, so users can define:

daemonUser in Debian := "deb-user"
daemonUser in RPM := "rpm-user"
daemonUser in Windows := "win-user"

I think if we had them appropriately delegate up the chain, it would be ideal.

You want the minimum amount of configuration REQUIRED with the maximum amount of flexibility.

If I get this right

val Debian = config("debian") extend Linux

daemonUser in Linux := "linux-user",

 // will override first one when calling debian:*
daemonUser in Debian := "deb-user"
