So, I looked through /var/log/boot.log for some reason and found that the random file system check for my root partition when booting is stopped.
cat boot.log | grep "Stopped"
gives
OK ] Stopped Switch Root.
OK ] Stopped target Switch Root.
OK ] Stopped target Initrd File Systems.
OK ] Stopped File System Check on /dev/disk/by-uuid/598d0acc-3340-43bf-b8d3-9d51da0b4128.
OK ] Stopped target Initrd Root File System.
OK ] Stopped Trigger Flushing of Journal to Persistent Storage.
OK ] Stopped Journal Service.
OK ] Stopped Entropy Daemon based on the HAVEGE algorithm.
That /dev/disk/… 128 should be my root parition.
Is that bad? I always thought it’s not a good idea to stop a file system check.
I also have a file system check for my /home partition afterwards, which is not stopped.
Because of the grep we see all “Stoped” messages together that may in fact be spread all over the file. I think it is more usefull to have a few lines before and after the line you worry about. That will show what happens at about the same time.

One possibility is that you have a failing disk, causing some of these to take too long. Maybe do some disk checking with “smartctl”. And this might be a good time for a backup.
