commit a2e7bbe6a98806d7749f6799abf42758c38c3f6b

    umount: add a umount utility
    
    This adds a umount utility that implements most of the functions that
    the Linux umount utility provides, especially that subset that is used
    by the Debian package initscripts.
    
    * utils/umount.c: New file.

commit bcca1a329595eb98e12d83f32fc7f5f0fc0bd379

    sutils: fix the semantic of -t, --types in fstab.c
    
    The mount utility on both Linux and FreeBSD allows one to either
    specify a whitelist or a blacklist of filesystem types to consider for
    --all. Prefixing the list with "no" indicates that the list is a
    blacklist. Furthermore, Linux' mount utility ignores a "no" prefix on
    any entry in the given list.
    
    Previously the Hurd variant first applied whitelist containing all
    positive values given and then filtered the resulting list using all
    negative values. But this makes little sense because each entry only
    has one value for the filesystem type (mnt_type) and all values are
    mutually exclusive.
    
    This patch adjusts the fstab handling code so that our mount utility
    behaves like the Linux mount utility. This code is used by both mount
    and fsck. The same argumentation applies to fsck as well.
    
    Like implemented in Linux mount, any "no" prefix is ignored to retain
    compatibility with the old behavior.
    
    * sutils/fstab.c (fstab_argp_create): Fix semantic of --types.

    sutils: allow multiple entries for the device "none"
    
    Previously it was not possible to add two mount entries with the same
    device information to an fstab structure. This is easily fixed by
    breaking the assumption, that there is only one possible mount entry
    for the "none" device as used by many purely virtual file systems.
    
    * utils/fstab.c (fstab_find_device): Return NULL if name is "none".

commit bf827fd801c76175d268b688f3bf9c757fa9e189

    mount: ignore mounted filesystems if --all is given
    
    Linux' mount utility ignores mounted filesystems if mount --all is
    invoked. This patch makes our mount do the same.
    
    utils/mount.c (main): Ignore mounted filesystems if --all is given.

commit 61c5d308d97dec46f856085b0cd07dfbd5c76a16
Author: Justus Winter <address@hidden>

    mount: implement -O, --test-opts
    
    --test-opts in combination with --all mounts only those filesystems
    with options matching the given set of options.
    
    Note that the semantic of the inverting "no" prefix differs from
    --types: While --types=nonfs,ufs means neither nfs nor ufs,
    --test-opts=nofoo,bar means not foo, but bar.
    
    * utils/match-options.h: New file.
    * utils/match-options.c: Likewise.
    (test_opts): New variable.
    (test_opts_len): Likewise.
    (match_options): New function.
    * utils/mount.c (parse_opt): Handle -O, --test-opts.
    (main): Use match_options as filter.

    mount: add -f and --fake arguments
    
    Add -f and --fake arguments. This makes our mount more compatible with
    Linux mount.
    
    * utils/mount.c (argp_opts): Add -f and --fake.
    (do_mount): Fake the translator startup if --fake is given.

    mount: fix mount -oremount with one parameter
    
    This fixes mount -oremount when just given the mountpoint, e. g.:
    
     % mount -oremount,ro /tmp
    
    * util/mount.c (main): Add a one-argument form for remount.

    mount: add -n and --no-mtab arguments
    
    Add -n and --no-mtab arguments. As we do not write an mtab file, this
    is a trivial patch that just ignores this argument to be more
    compatible with Linux mount.
    
    * utils/mount.c (argp_opts): Add -n and --no-mtab.
    (parse_opt): Do nothing on 'n'.
