Hello. I want to use a USB stick, but it never appears in fstab. Nor can I
use genfstab; it's not installed. Please, can someone tell me which package
contains genfstab, or how to search apt for it?
/etc/fstab is a file that the system administrator (you) is expected to
maintain. But, you don't need an fstab(5) entry to access a USB stick.
If you are using a graphical desktop, the USB stick should be
"automagically" mounted when inserted. Be sure to right-click and
"eject" the USB stick before removing it.
If you are using the console or a terminal, log in to the root account.
Connect your USB stick.

Note "[sdb]" in the last six lines. The device node corresponding to
the USB stick on my machine is /dev/sdb. On your machine, it could be
sdb, sdc, sdd, etc., or even sdb1, sdc1, sdc1, etc.. Use that value in
place of 'sdb' for the following commands.
Use mkdir(1) to create a mount point:
2018-12-30 21:27:11 root@tinkywinky ~
# mkdir /mnt/sdb
Use mount(8) to mount the USB stick file system:
2018-12-30 21:27:18 root@tinkywinky ~
# mount /dev/sdb /mnt/sdb
You should now be able to navigate to the file system on the USB stick.
2018-12-30 21:37:45 root@tinkywinky ~
# cd /mnt/sdb
2018-12-30 21:38:24 root@tinkywinky /mnt/sdb

When you are done, change your working directory back to home:
2018-12-30 21:41:08 root@tinkywinky /mnt/sdb
# cd
umount(8) the USB stick:
2018-12-30 21:44:08 root@tinkywinky ~
# umount /mnt/sdb
Remove the USB stick.
