-As time syncronisation is important, you should configure ntp servers in `/etc/systemd/timesyncd.conf` and make them match with the entries in `/etc/rc.local` iptables configuration
+And add the `noatime,usrjquota=aquota.user,jqfmt=vfsv1` options to the `/home` mountpoint (if not a separate partition, the `/` mointpoint and `noatime`to `/`. Then initialize quota (replace `/home` with `/`, if you do not have a separate partition):
+```
+mount -o remount /home
+quotacheck -cMu /home
+quotaon /home

+In some cases, you might get an error, that quota is not supported. This is usually the case in virtual environments. Make sure you have the full kernel installed, not one with a `-virtual` package. They usually are `linux-image-amd64`, `linux-image-arm64` or `linux-image-generic`, depending on your distribution. Also make sure, you are running a real virtual machine (e.g. KVM). Some providers sell containerized VPSes (e.g. OpenVZ), which means you don't run your own kernel...
