Why are other partitions loaded?

Wondering why two of my other partitions ( sda4 & sda6) automatically are loaded ?
.
.
sda4 was my separate partition for older /home/
as storage for back-ups.
.
.
sda6 is my / for “Ubuntu 22.04.3 LTS”

Those are probably mounted by your desktop software.

What desktop environment are you using?

Am mosty using openSUSE Leap 15.5

Occasionally Ubuntu.

.

Have cautiously copied using Yast to view Boot Loader Settings

Boot Loader Settings 
    Boot Loader = Grub2 

Boot Code Location 
   [] Write to Partition (/dev/sda2) 
   [Y] Write to Master Boot Record   (/dev/sda2) 
   [] Custom Boot Partition 

  [Y] Set Active Flag in Partition Table for Boot Partition 
   [] Write generic Boot Code to MBR 

Protective MBR Flag 
[do not change] 
[Edit Disk Boot Order]

When I asked about “desktop environment”, I was asking whether you are using KDE or Gnome or XFCE or whatever. They behave differently for user mounting of partitions.

I’m not suggesting that your boot loader settings are relevant to the issue.

am long term GNOME user 41.8

Looked at another desktop with a similar setup, which is also used.

Main difference is the other machine shows EFI for both openSUSE and Ubuntu, while this machine on openSUSE does not show EFI.

Will reboot then log into this machines’ Ubuntu to see IF it shows EFI.

.

The mounted filesystems have nothing to do with grub or your bootloader.

They were probably picked up and added to /etc/fstab. You can look there, and if they’re there and you don’t want them mounted, comment out the lines (or delete them; I’d recommend commenting them out in case you want to add them back in later for some reason) and then reboot.

Multibooters commonly wish for access to everything regardless which OS is currently booted. Various setup tools make various assumptions about whether a user actually has that attitude, and may or may not agree on whether, or where, to mount a filesystem not required by the booted OS. If you wish something specific with particular filesystems, you can exercise your administrative power by configuring them in /etc/fstab or using udev. Otherwise just let the setup tools do what they please. :smiley:

Nice to hear. I never use Gnome.

Presuming a default configuration of the system you are talking about mounts at /run/media/ are typically governed by the device notifier:

Read the fine documentation.

Thanks :- )

Self unsure what was happening, when extra partititons automatically appearing on main FILES list

Usually they were NOT loaded, though were shown in FILES “Other Locations”

Liked that, so when as clear , until another partiiton mounted when it appeared on main FILES list so knew it is mounted.

When I un-mount I do use e2fsck /dev/sda? for which-ever partition it was.
