comment MySQL aborting during initial db installation
third-party packages for debian (and other distros) are almost-universally awful. There are notable exceptions but, generally speaking, even when they're made by the developer of the software, they're rarely made with any real attempt at systems integration with the target distro and are far more often made with the attitude that 'our program is super-special and doesn't have to play nice with others'.

comment Install single debian experimental packages?
IMO your best option would be to just switch to debian jessie aka testing, and apt-get install openbox (and related packages) to keep the same openbox-based UI. or use xfce. or maybe lxde.

comment Open screen process in terminal from script
Note that you could just run start-minecraft.sh in a new screen window with screen -S main -X screen -t minecraft /path/to/start-minecraft.sh but when that command terminates, the screen window will close. opening a shell and then pasting a command into it allows the screen window to stay around until the shell exits.

comment Open screen process in terminal from script
If you have an existing screen with session name 'main', then you can create a new window in that session with the title 'minecraft' with screen -S main -X screen -t minecraft. You can then tell it to run a command - e.g. start-minecraft.sh with screen -S main -p minecraft -X stuff '/path/to/start-minecraft.sh^M'. Note that the ^M is a Ctrl-M character (i.e. in bash, type Ctrl-V Ctrl-M).

the trouble with caring about UUoC is that in cat is often just a placeholder for any other command or pipeline that produces output.

comment Swap separation for multiple distributions
BTW based on what I read in the Arch Suspend/Hibernate page I mentioned, it's probably best to add 'noauto' to the /etc/fstab lines for unwanted swap partitions rather than delete them - that should prevent systemd or anything else from automatically re-adding the swap devices if it finds them.

2. if you are using systemd rather than sysvinit or upstart, then it will use all swap devices that it can find by default. As well as editing /etc/fstab you probably also need to configure systemd to only use one of the swap devices. I'm not familiar with systemd so can't give any details on how to do that.

comment Swap separation for multiple distributions
+1, good answer. two more points to be aware of: 1. you need to tell the kernel for each distro which swap device it should use to resume. you can do this in your grub config - e.g. if ubuntu uses /dev/sda3 as swap then add resume=/dev/sda3 to the GRUB_COMMAND_LINE_LINX="..." variable /etc/default/grub (create the line if it doesn't already exist). Do the same for Arch and Fedora (except use their dedicated swap partitions). Arch Linux has, as usual, great documentation at wiki.archlinux.org/index.php/Suspend_and_Hibernate (tailored for Arch but useful for any distro).

comment mdadm with overlaying lvm - remove a hard drive
@psusi: that's a matter of opinion, not fact. by any objective measure, zfs is very well supported on linux - installing a dkms or similar package for any major distro is a trivial exercise. btrfs isn't quite ready for production use in a real server room, but it's good enough for home use. just as with raid, neither zfs nor btrfs is a substitute for regular backups.

comment mdadm with overlaying lvm - remove a hard drive
i didn't read it in there. that's exactly why i felt it was necessary to point out the risk. it's a big enough risk that it deserves a warning.

comment mdadm with overlaying lvm - remove a hard drive
the question was also about ...I'm just evaluating in which way I should configure my hard drives for my home-server... - knowing about other options is useful when deciding what to do. btw, zfs can stripe across multiple disks, it would be pretty useless at its primary job if it couldn't.

comment mdadm with overlaying lvm - remove a hard drive
there is no magic solution, there are just tradeoffs you can choose between. flexibility, error correction, snapshotting etc in zfs or btrfs. or enhanced risk or reduced performance if using partitions as you suggested (which is not a bad solution, it just has some potential issues you need to be aware of)
