When I plug flashdrive it gets automounted. Upon web searching I found only two ways it's done in Linux: autofs and using systemd. E.g. rather recent (2017) post: systemd-automount-vs-autofs
However, I could not find neither autofs installed nor file /etc/systemd/system/mnt-scratch.automount (no files with auto in /etc/systemd).
/etc/fstab also does not have any info on automount, just fixed filesystems.
I want to change options of file system being automounted like in fstab. How to find out how automouting is done and change options?
P.S. I'm using Linux Mint now but knowing more general way to do the task is preferred.
