3 # Sector size is the smallest unit of data which can be read or written.
4 # Making it too small decreases performance and decreases available space.
5 # Making it too large may prevent filesystems from working. 512 is the
6 # minimum and always safe. For UFS, use the fragment size
11 # Start and end of the encrypted section of the partition. Specify in
12 # sector numbers. If none specified, "all" will be assumed, to the
13 # extent the value of this can be established.
20 # An encrypted partition can have more than one key. It may be a good idea
21 # to make at least two keys, and save one of them for "just in case" use.
22 # The minimum is obviously one and the maximum is 4.
27 # Flushing the partition with random bytes prevents a brute-force attack
28 # from skipping sectors which obviously contains un-encrypted data.
29 # NB: This variable is boolean, if it is present it means "yes" even if
30 # you set it to the value "no"
