I'm still puzzled by the fact that the distribution chose to do this

* También depende del entorno gráfico: #gvfs (#gnome, #xfce) o el equivalente en #kde (creo que es #kio), que suelen montar en /run/media.
* Configuraciones personalizadas de #polkit pueden hacer que los usuarios puedan montar discos en diferentes ubicaciones.
* El mismo udisks2 permite cambiar configuraciones para montar automáticamente en otros directorios.
* Y por supuesto, el montaje manual y uso de /etc/fstab puede permitirnos montar directorios no estándar.

One thing that I think we've lost over the last 20 years is "audio cues" #linux #foss #kde #gnome #opensource -- the desktop used to give a lot more audio feedback as to the events & status of events.
Empty the recycle bin? It had s simple audio cue play
Copy a folder? You have a audio cue to communicate success.
New email? Cue AOL charming & cringy "You've got mail.wav"
OS Startup? You feel like you are getting excited to get something done withe Windows XP - 7 and early 2000s Ubuntu startup sounds.
I think this principle could be taken so much farther -- perform a #rsync Why not have a audio cue for both Success.ogg and Failure.ogg -- or what about #polkit password verification, you are multi tasking on the phone or doing something in your office -- having a cue to redirect your attention to that you need to enter a password would be helpful.
Same thing goes for #pacman #yay and #paru in #archlinux
There are times you are compiling a program and it needs extra privileges to install but you don't notice it -- it would make a huge difference if we had a hook system and could Enable/Disable audio cues & notifications -- that would be a huge improvement.
I could really see this also bringing a lot of value in #linuxphone space, with #ubuntutouch #postmarketos #sxmo and others.
Its really hard to know what your missing when its been so long since you had it.
Plug in a USB Flash Drive? Audio Cue
Connect / Disconnect your phone to your computer? Audio Cue
Remote SSH Connection logs into your machine? Notification & Audio Cue.
With the right sound packs there is so much room for improvement -- #steamdeck #steamos v3 does a good job with this too giving subtle cues as you navigate the UX, startup, shutdown, etc...
