mount.crypt
mount.crypt(8) pam_mount mount.crypt(8) Name mount.crypt - mount a dm-crypt encrypted volume Syntax mount.crypt [-nrv] [-o options] device directory Options -o options Set further mount options. mount.crypt will take out its own options it recognizes and passes any remaining options on to the under- lying mount program. See below for possible options. -n Do not update /etc/mtab. Note that this makes it impossible to unmount the volume by naming the container - you will have to pass the mountpoint to umount.crypt. -r Set up the loop device (if necessary) and crypto device in read-only mode. (The mount itself will necessarily also be read-only.) Note that doing a remount using `mount /mnt -o remount,rw` will not make the mount readwrite. The crypto and loop devices will have to be disassociated first. -v Turn on debugging and be a bit more verbose. Mount options cipher The cryptsetup cipher used for the encrypted volume. This option is mandatory. pmt-ehd(8) defaults to creating volumes with "aes-cbc-essiv:sha256" as a cipher. dm-timeout=seconds Wait at most this many seconds for udev to create /dev/mapper/name after calling cryptsetup(8). The default value is 0 seconds. fsck Run fsck on the container before mounting it. fsk_cipher The OpenSSL cipher used for the filesystem key. fsk_hash The OpenSSL hash used for producing key and IV. fstype The exact type of filesystem in the encrypted container. The default is to let the kernel autodetect. keyfile The path to the key file. This option is mandatory for "normal" crypto volumes and should not be used for LUKS volumes. remount Causes the filesystem to be remounted with new options. Note that mount.crypt cannot switch the underlying loop device (if applies) or the crypto device between read-only and read-write once it is created; only the actual filesystem mount can be changed, with lim- its. If the loop device is read-only, the crypto device will be read-only, and changing the mount to read-write is impossible. Sim- ilarly, going from rw to ro will only mark the mount read-only, but not the crypto or loop device, thus making it impossible to set the filesystem the crypto container is located on to read-only. ro Same as the -r option. verbose Same as the -v option. Obsolete mount options This section is provided for reference. loop This option used to set up a loop device, because cryptsetup(8) expects a block device. The option is ignored because mount.crypt can figure this out on its own. pam_mount 2008-10-08 mount.crypt(8)
