DESCRIPTION
NOTE! This manual page has been generated from a common source shared between all rump(3) file servers. Some parts of this manual page may not apply to this particular server. After reading this manual page, you may want to verify the details from mount_smbfs(8).
 
The rump_smbfs utility can be used to mount smbfs file systems. It uses rump(3) and p2k(3) to facilitate running the file system as a server in userspace. As opposed to mount_smbfs(8), rump_smbfs does not use file system code within the kernel and therefore does not require kernel support except puffs(4). Apart from a minor speed penalty (starting from 10% and depending on the workload and file system in question), there is no difference to using in-kernel code.
 
In case mounting a file system image from a regular file, rump_smbfs does not require the use of vnconfig(8) unlike kernel file systems. Instead, the image path can be directly passed as the special file path. The exception is if the image contains a disklabel. In this case vnconfig is required to resolve the start offset for the correct partition within the image.
 
It is recommended that untrusted file system images be mounted with rump_smbfs instead of mount_smbfs(8). Corrupt file system images commonly cause the file system to crash the entire kernel, but with rump_smbfs only the userspace server process will dump core.
 
To use rump_smbfs via mount(8), the flags -o rump and -t smbfs should be given. Similarly, rump_smbfs is run instead of mount_smbfs(8) if “rump” is added to the options field of fstab(5).
 
Please see mount_smbfs(8) for a full description of the available command line options.
