Mount default behavior

Expect · 07-12-2013, 10:28 AM

Hello :-)
If I execute the mount command without the dash t (-t) option, what is the default mount option that occurs?
I am asking this since I wonder how the execution of a (cifs) mount works this way:

Code:

mount -o options username=user,password=pass,workgroup=domain.com //ip.add.re.ss/share /my/mount

without adding the mount option, it is mounted as cifs.
I always thought the default one was NFS.
any ideas?

Here is way "man mount" says:

Quote:

If no -t option is given, or if the auto type is specified, mount will try to guess the desired type. Mount uses the blkid library for guessing the filesystem type; if that does not turn up anything that looks familiar, mount will try to read the file /etc/filesystems, or, if that does not exist, /proc/filesystems. All of the filesystem types listed there will be tried, except for those that are labeled "nodev" (e.g., devpts, proc and nfs). If /etc/filesystems ends in a line with a single * only, mount will read /proc/filesystems afterwards

But of course the device type possibly indicated in /etc/fstab will be considered.
