To always mount a Virtual Box "shared folder" on booting an Ubuntu guest we have two options. It is up to personal preference which option works best in our setting.
1. Mount with fstab
To mount a shared folder using the
vboxsf filesystem provided with Guest Additions we first need to make sure prerequisites are met. Then we may put the following line in our
<name_of_share> /path/to/mountpoint vboxsf <options> 0 0
/path/to/mountpoint with your individual setup (the directory for the mountpoint has to be created first). See the manpage for mount for mount
<options>. One possibility is to mount with
defaults, or to give specific mount options (e.g.
rw, suid, exec, auto, users).
On some systems the
vboxsf kernel module is not yet loaded at the time
fstab is read on boot. It may then help to append the
vboxsf kernel module to
2. Mount with Virtual Box "automatic mounting":
In recent releases of Virtual Box we can also automatically mount shared folders on creation:
After a reboot of the guest this shared folder will be mounted to the guest directory
/media/<username>/sf_<name_of_share> accessible to all users who had been made member of the group
