`sanity-squashfs` available and removed notifications

[tetra...@danwin1210.me]

Dom0 device notifications (same style as when attaching a USB stick)
keep popping up, along the lines of:

/tmp/sanity-squashfs-290* (deleted) is available
/tmp/sanity-squashfs-290* (deleted) is removed

As far as I know there is no update process running in the background.
journalctl in dom0 doesn't show anything useful either.

Does anyone know what this is?

A quick search reveals that it might be from snapd (snapcraft). Every time a Qube tries to attach a file to a loop device -- perhaps to mount its filesystem -- it's still recognized as a block device (just like a USB flash drive as you mentioned) and a udev script notifies the Dom0 about the event.

If it continues to bother you, just create a '.qubes-exclude-block-devices' (without the quotes) file in the /tmp directory. It should silence all loop attaches from it, not just sanity-squashfs-290*. Should it not work, you can kill the Qubes block devices tray icon process which is afaik responsible for all the notifications iirc.
