remove unnecessary packages from OS install #9

Closed prjemian closed 3 years ago

prjemian commented 3 years ago

After the OS is installed but before the first update, remove the largest of the packages that are not used by the training software.

Includes:

Do this before installing updates or the training stack since the total size of the VM image never decreases. (The host storage used by the VM expands to fit the content of the VM as installed.)

prjemian commented 3 years ago

new installed, LinuxMint 20.1 takes 8.4GB

Using Disk Usage Analyzer, largest consumer is /usr (6.0 GB) in which /usr/lib (3.4 GB), in which /usr/lib/libreoffice takes 339.0 MB. /usr/lib/thunderbird takes 210.1 MB, /usr/share/libreoffice has 306.4 MB

NOTE: need the guest additions and bidirectional clipboard to make this MUCH easier
