Installation partition too small

Asked by bhaskar

Hi,
Today i had installed Ubuntu 16.10 into my Dell inspiron. The mistake what I did is root partition was kept 20GB and home partition has kept 30GB. Now I understood that 20GB is too small for installing stuff in ubuntu and i already used 60% of space in root partition. Can you tell me the solution for if i want to install more than 20GB in ubuntu in future and definitely it will go beyond 20GB after forming log files and variable data in ubuntu.

20Gb is plenty with management. If you remove unused kernels and unused applications you can make a small installation.

My root partition uses about 3Gb of space...

I understood your answer but still i want some clue for the above problem. Because in windows if C:drive overflows then we can change the installation path to D:drive during installation setup like that any feature available for ubuntu i want to know.

Linux uses a flat file structure. It does not use constructive drive letters like in Windows.

When you want to access a file system, be it USB stick or data CD or partition on an internal drive it is mounted to a folder. The standing data (if any) in a mount point will be inaccessible after the mount. When you access the folder, the kernel knows to start reading the other file system.

When you install deb files, the data will be put in the places dictated in the deb, you cannot tell it to use a different partition due to the point I made above.

If you manually install applications you may find they go into /opt which you could possibly symlink to a folder in /home and the real storage will occur on the other partition. This use of /opt is rare in Ubuntu
