Hm... do you mean being started from the command line, or with SYSV script instead of systemd? Karaf by itself works fine without being started by systemd or SYSV init for that matter. Karaf can be started from the command line and result in the same console one sees when SSHing in. But the way I've packaged it the start from command line behaviour isn't easily accessible (and also easily combined with the daemon behaviour, ie. diretories owned by user karaf. A karaf started from the command line is typically used for development and run as the developers user). I don't much like systemd myself. But I just figured "if there are two alternatives, pick one, and pick the one most likely to be used in the future". Switching to SYSV wouldn't be hard (copy the SYSV scripts from the source tarball and remove the disabing of SYSV maintscript generation, and remove the use of systemd). What's preferred from a debian viewpoint? SYSV? Or systemd? >> logging to /var/log/syslog and using the following directories: >> KARAF_ETC = /etc/karaf/ >> KARAF_HOME = /usr/share/karaf/ >> KARAF_DATA = /var/lib/karaf/data/ >> all directories are owned by user karaf, group karaf > /etc/karaf should be root-owned.

The directory has to be karaf-writable, because karaf allows configuration changes from the karaf console command line as well as from the API. There is one file that contains secrets (and that file does not have to be writable by karaf, I think. But it has to be readable by karaf). Applications may create their own configuration files in this directory, so karaf needs to be allowed to create new files here. > /usr/share/karaf MUST be root-owned, it is NOT writable > during normal system operation (admins MAY mount /usr as > read-only filesystem). Hm... that's harder. Karaf creates stuff under $KARAF_HOME/instances/ One way of doing it would be to switch KARAF_HOME to /var/lib/karaf/ But there are stuff in KARAF_HOME that are read-only: the jar files (or symlinks to jar files) in $KARAF_HOME/lib and $KARAF_HOME/system. Would it be proper to install these under /var/lib/karaf/? Or would it be best to leave them where they are, under /usr/share/karaf but to create symlinks to them from /var/lib/karaf/ ? >> IMO I'm not sure if this is worth the effort, because the karaf jar >> files aren't really meaningful outside of karaf, or in a version >> independent manner > I agree.

Ok, I will try to create an official state package, when/if the dependencies becomes available (and maintain it going forward, if noone else wants to). > Also: I’m impressed with the amount of work you did to > document this all! Hats off. Thanks! :-) It was actually quite fun. And also easier to use the standard debian tools than fpm that was used to package the package I found and forked when googling for "karaf debian package", back in November 2016. (I guess it helped that I was familiar with make and GNUMakefile syntax so that the debian/rules file syntax wasn't a mystery).
