Same systemd often hang at shutdown and I cannot be bothered to understand why.

My biggest issue with systemd is the log system. It is so stupidly slow, that I don't think it is possible to make it that slow without purpose. It literally takes minutes to grep though logs on any of my machines with journalctl.

In fact it is so slow. It is faster to first eat the few minutes to extract the logs into a text file. Which I can then grep through in milliseconds.

Oh and the raw text file takes less space than the systemd log database!
