Automatic mount of external HDD.

[Erik P. Olsen]

I have an external 2TB HDD which is defined in /etc/fstab so it is mounted at system boot
time. I would like to be able to have it mounted automatically with the same mount point
as defined in fstab when it is hot-plugged and unmounted when it is later disconnected.
Is that possible and if so how to do it?

Thanks in advance.

There are tools like usbmount which mount drives as they are plugged in.  
They have their own mount area.

You could write a script which uses lsblk (I like "lsblk -bfr") to watch 
for drives and act on them (eg to just go "mount mountpoint" when you 
see that device show up).

And I think some GUI desktops run their _own_ automount stuff, which 
will race with you.

my 2c

if you use a Workstation version:

- create e file under "/etc/udev/rules.d" (eg. 99-udisks.rules) insert the following line

ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1"

the disk will be mounted under /media and not under /run/user/....

/media/<label>

- as root: copy the content of /usr/lib/systemd/system/tmp.mount in
   /usr/lib/systemd/system/media.mount (edit and correct all occurrance of /tmp in /media)

Thanks for pointing me to udev. This is definitely the way to go.
