Ubuntu Clean Up

From Ever changing code

If you are using Ubuntu for various Linux projects you will find that as it comes with pre installed with many packages. On the other hand installing just minimal version seems to be too extreme. Therefore I started maitaining a list of unnecessary packages and one liner to that removes them all. Please feel free to modify for your needs.

Default partitioning

On virtual systems schema below will be applied, eg on laptops:

#Eg. for 4G memory and 50G storage system

/dev/mapper/ubuntu--vg-root        mount_point: /
 /dev/sda1 (50G)

LVM VG ubuntu-vg, LV root    as ext4
LVM VG ubuntu-vg, LV swapt_1 as swap

#Boot device:

As a good handy practice you may create 100G virtual disk that you thin provision. Then create 2 PVs for root and swap partitions. Don't utilize all space at once but extend partitions when needed. This method eliminates adding new disks to VMs saving time and efforts.

Example LVM setup, here using 30G Physical Volume(99.9% used), 1 Volume Group and 2 Logical Volumes (root and swap).

$ sudo pvs
  PV         VG        Fmt  Attr PSize   PFree 
  /dev/sda1  ubuntu-vg lvm2 a--  <29.93g 36.00m
$ sudo vgs

  ubuntu-vg   1   2   0 wz--n- <29.93g 36.00m
