Introduction
Trying to find the lowest possible disk usage for an Ubuntu Server installation, ready for a NAS.
Package Clean
Clean the apt cache, install some apps to clean other apps, remove the cleaning apps, then clean the apt cache again...
sudo apt-get autoremove && sudo apt-get clean all && sudo apt-get autoclean all sudo apt-get localpurge sudo apt-get install deborphan sudo localepurge sudo sudo deborphan --guess-all sudo sudo deborphan --guess-all --all-packages sudo apt-get purge installation-report sudo apt-get purge usbutils sudo apt-get purge pciutils sudo apt-get purge localepurge sudo apt-get purge deborphan sudo apt-get autoremove && sudo apt-get clean all && sudo apt-get autoclean all
Now check what disk usage we are left with (down to 830Mb)...
sudo df -H -T -x devtmpfs -x tmpfs Filesystem Type Size Used Avail Use% Mounted on /dev/sda1 ext4 7.8G 830M 6.6G 12% /
Where the space is being used...
sudo du -mcsh --exclude=/media --exclude=/mnt --exclude=/proc --exclude=/sys /* |sort -h 0 /dev 0 /initrd.img 0 /vmlinuz 4.0K /lib64 4.0K /opt 4.0K /srv 8.0K /media 8.0K /mnt 16K /lost+found 16K /root 32K /tmp 36K /home 1.8M /run 3.5M /etc 5.2M /sbin 9.6M /bin 25M /boot 114M /lib 252M /var 367M /usr 776M total
