Any suggestions? I don't actually understand the umask=022
umask sets the default permissions by subtracting the mask from the maximum. 777 is maximum for directories: it gives directory / executable rights, plus read and write: 1 - execute / change into this directory - x 2 - write - w 4 - read only -r You add the numbers together to get the permission value. So: -rw-r--r-- is a common default for user files. It's 644, it allows the user to read and write, others only to read. drwxr-xr-x is common for directories. The d indicates directory, the user can read, list/change into and write (delete / create new files) in the directory. Others can only read and cd. This is 755. -rwx-r-xr-x is a possible value for user scripts when you don't want to have to specify bash or perl in front, just ./scriptname So for directories: 777 - 022 gives 755 The maximum for files is taken from 666 (executable files not being a default), so 022 gives 644. umask 022 therefore sets files to 644 and directories to 755 - the usual default for user space.
bit, just copied it from a website where someone said they achieved what I'm attempting by replacing 'noauto' with 'umask=022'
However, this doesn't answer the original point - you saw this on a website that said to replace noauto with umask? The two are completely different. noauto means that it won't be mounted by default at system start up. You will have to mount it yourself later. Usually, that's best done by adding user to the noauto command and is used for CDROM's, USB sticks and other removable media that might not be there at boot. You can also use it if that partition is optional - no system files are stored there, nothing that is needed to start the system or login the user.
in those two lines.
