FreeBSD chroot(2) fails with EPERM when a directory file descriptor is open
with either `kern.chroot_allow_open_directories` being 0, or when the process
already is inside a chroot. This is exposed in alpm_run_chroot that uses
opendir() to open a file descriptor to the current directory before doing
the forking and chrooting. Since the file descriptor is not used in the
forked process, we close it.

On operating systems we support, the behavior is always such that the
kernel will do the right thing as far as invalidating the file
descriptor, regardless of the eventual return value. Therefore,
potentially looping and calling close multiple times is wrong.
At best, we call close again on an invalid FD and throw a spurious EBADF
error. At worst, we might close an FD which doesn't belong to us when a
multi-threaded application opens its own file descriptor between
iterations of the loop.

On upgrades, indirect dependencies were not being detected if there was
a dependency in between them that was not part of the transaction. For
example, with the dependency chain: pkg1 -> pkg2 -> pkg3, if pkg1 and
pkg3 are being upgraded but not pkg2 pacman would not order pkg1 and
pkg3 properly.
This was particularly problematic when replacements were involved
because the replaced package(s) would be removed at the start of the
transaction. If an install script required the replacer and lacked
a direct dependency, it could fail.

Packages removed due to conflicts are always removed at the beginning of
the transaction and as such can be included in the check for whether all
owners of a directory will be removed in a transaction. Installed
versions of packages being upgraded, other than the one with the

intelligent enough to ensure that they are removed prior to the
installation of the conflicted package.

Arch Linux typically runs into this with /sys when upgrading the
filesystem package in build chroots, but LXC users might also run into
this, since their /sys is shared from the host and must, for security
reasons, be mounted RO.
I've neglected to add any tests for this because they would require root
in order to run. Current tests all pass with this patch and I've
confirmed the desired behavior in a VM. Incidentally, the first hunk of
this patch (skipping can_remove_file checks for directories) resolves the
case of API mountpoints being removed since they eventually fall into
unlink_file and fail with "contains files". However, this patch should
still be the Right Thing To Do™, as we can't possibly remove a directory
