About to get access to a CD through the terminal - with Virtual Box working with Ubuntu Desktop and Server, when the Guest Additions .iso file is inserted through:
Devices->Insert Guest Additions CD image
For the Desktop environment its access is through /media/<username>/VBox_GAs_#.#.# and for the Server environment its access is through /dev/cdrom, it to be mount it with the sudo mount /dev/cdrom /cdrom command.
Observe the difference between /media and /dev
Question
- Why the CD access in Ubuntu Server is different than expected according with FHS?
I assumed it should be /media too - it taking in consideration again the FHS - it according with:
Note this situation happens for the 18.04LTS and 20.04LTS
/cdrom. Nobody stopped you from mounting it at/mediaor wherever. Even on Ubuntu Desktop, if you check the device that's mounted at/media/<username>/VBox_GAs_#.#.#, it will be/dev/cdrom*.isofile - automatically the path is generated to that location. Same as for the Server Environment - I mean, I must use/dev/cdromto mount - well - is/cdromcorrect? I used thesudo mount /dev/cdrom /cdromcommand according with a tutorial to install the VB Guest Additions - for Desktop and Server environments/dev/cdrompath to mount in the desktop environment?Devices -> Insert Guest Additions CD imageis accomplished in the Desktop Environment appears a CD icon in the Desktop, then I open a new terminal, the location of theGuest Additioncontent - of the CD - is/media/<username>/VBox_GAs_#.#.#- important to notice that I did not mount nothing manually/media/<username>/VBox_GAs_#.#.#. And when you mount the CD manually at/cdrom, the content is at/cdrom. Yet, you are for some reason comparing/media/<username>/VBox_GAs_#.#.#with/dev/cdrom. Why? How are those two equivalent?
