The release v2.22 (the new umount) introduces a regression when root
fs is excluded from umount --all. There is not reason for this
exception. The libmount should be smart enough to disable mtab update
after rootfs umount.

We use
mnt_optstr_append_option(&o, mnt_fs_get_vfs_options(fs), NULL);
in mount.nfs, unfortunately mnt_optstr_append_option() has been marked
ass nonnull(1, 2). That's wrong because append and prepend should
robust enough to accept NULL as option name.
The patch also removes almost all __attribute__((nonnull). It seems
better to rely on assert() to have usable feedback. In many cases
(nonnull) is premature optimization for the library. This attribute
makes sense for things like strlen() or so...

Linux kernel does not allow to change more than one propagation flag
by one mount(2) syscall. The flags also cannot be mixed with another
mount options. It means that the propagation flags cannot be stored in
/etc/fstab, manual "mount --make-* <mountpoint>" is always necessary
after successful mount. Painful...
This patch implements additional mount(2) after previous successful
mount(2) (or exec /sbin/mount.<type>).
For example:
mount /dev/sda1 /A -o private,unbindable,ro
or fstab entry:
/dev/sda1 /A auto ro,private,unbindable
is implemented by three mount(2) calls:
- 1st mounts /dev/sda1 with MS_RDONLY
- 2nd sets MS_PRIVATE flag
- 3rd sets MS_UNBINDABLE flag.
It's the same as as to manually call:
mount /dev/sda1 /A -o ro
mount --make-private /A
mount --make-unbindable /A
This solution is not atomic, and umount(2) is not called if
propagation flags are not successfully applied, only error is
returned.
This change does not affect libmount API, so one beautiful day when
mount(2) syscall will be improved we can drop this nasty patch.

15 1 0:13 / /sys rw,nosuid,nodev,noexec,relatime - sysfs sys rw

17 1 0:14 / /run rw,nosuid,nodev,relatime - tmpfs run rw,mode=755
This causes an infinite loop in mnt_table_next_child_fs, and is

Since nodev FSs have no backing block device, it's unreasonable to try
and resolve the source back to a path on the filesystem. Always trust
the source of the FS given in /etc/fstab to avoid remounting the device
when a directory of the same name exists in the current working
directory.

# mkdir /foo
# echo 'foo /foo tmpfs defaults 0 0' >> /etc/fstab
# mount -a
# cd /root; mkdir foo
# mount -a
# mount | grep /foo

Duplicate text is dealt by referring to license files. The `pg'
command does not need separated license file because the source
file has same text at top of it.

The path resolving function breaks when handling undefined sources
("none") used by pseudo-filesystems. The assertion is causing the
samples/mount program to abort:
dave@offbook:~/projects/util-linux-good/libmount/samples$ ./mount
/dev/sda3 on / type ext4 (rw,errors=remount-ro,commit=0)
proc on /proc type proc (rw,noexec,nosuid,nodev)
lt-mount: cache.c:464: mnt_resolve_path: Assertion `path' failed.
Aborted
/etc/mtab:
/dev/sda3 / ext4 rw,errors=remount-ro,commit=0 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
none /sys sysfs rw,noexec,nosuid,nodev 0 0
fusectl /sys/fs/fuse/connections fusectl rw 0 0
none /sys/kernel/debug debugfs rw 0 0
...
Instead of this assert on NULL we can simply return NULL and let mnt_pretty_path do the work.

tab_parse.c:mnt_parse_mountinfo_line parses "none" in src as NULL,
tab_update.c:fprintf_mtab_fs sets m1 to NULL instead of "none" and
returns -ENOMEM
tab_update.c:update_table says "write entry failed: Success", as errno
hasn't been set, and gotos to leave, leaving mtab not updated.

This is libmount based re-implementation of the mountpoint(1) command.
The original implementation is maintained in sysvinit suite.
The mountpoint(1) in util-linux is not enabled by default (for now) --
use --enable-mountpoint to enable the util.
