  CHANGELOG: document mkinitcpio v34

Use consistent shebangs:

* `#!/usr/bin/env bash` for bash,
* `#!/usr/bin/ash` for ash,
* `#!/bin/sh` for POSIX sh,
* `#!/usr/bin/env bats` for bats.

Fixes #147

Calling them binaries is not correct. They could be called executables,
but since we do not enforce the execute (`+x`) permissions on the added
files, it would be wrong too.
Since they have shebangs, they are scripts, so let's call them that.

138374f0 added a condition to
`add_binary` that if the non-binary file does not have a shebang, the
function returns successfully before trying to parse sodeps. Before the
change, the function returned in all cases when the file was not a binary.

Bring back the previous behaviour of returning early on non-binaries.

Fixes 138374f0

`initialize_buildroot` treats `none` specially by not creating the kernel
directory. Use it instead of `0`.

Fix up 657bfd62.

Use `realpath` to resolve the target file and add it as regular file with
`add_runscript`. Otherwise, if the hooks are symlinks, the initramfs image
could expose the paths used on the host system.

38a62e22 broke support for adding files
via nested symbolic links.
Before the change, the first level symlink was pointed to the end target,
but after the change it pointed to the second symlink which was not added
to the initamfs.

Recursively adding each nested symlink is not possible since any directory
in the next target's path could itself be a symlink. Parsing it all is not
sanely possible.
Instead limit relative symlink support to target that are not symlinks and
reside in the same directory.
Everything else will get pointed to the resolved end target.

* Rename *_efi_image preset variables to *_uki.
* Rename option --uefi to --uki.

The old variables and options will still keep working, but will not be documented anymore.

Fixes #134.

Executables that are actually only scripts require the binary that is
specified in the shebang to be able run.

The `add_binary` function will only warn and not automatically include the
required interpreter.
This is because with things like `#!/bin/sh`, it may be better to use the
`base` hook that provides it instead of pulling in the `bash` binary.
Also it is possible that the interpreter is simply added after the binary
that requires it. That is why it says "Possibly missing".

Fixes #136.

  mkinitcpio: update the "sane PATH" to remove symlinked directories
  functions: use the -f/--force option when copying files with add_file

`compgen -c` from the `fsck` hook will look for files in all directories
in PATH. Including those that are just symlinks to already defined ones.

This makes it run four times longer than necessary and needlessly
overwrite existing files.

Use Arch's default path that omits the `/usr/sbin`, `/sbin` and `/bin`
symlinks.

When `mkinitcpio` is executed as a regular user instead of root, sometimes
it will fail to overwrite files in the work directory.

For example, with a build hook containing:

    add_binary /usr/bin/dmsetup
    add_binary /usr/bin/dmsetup

The `mkinitcpio` output will contain:

    cp: cannot create regular file '/tmp/mkinitcpio.XOuS4Z/root/usr/bin/dmsetup': Permission denied

Using the `cp` command's `-f`/`--force` option instructs it to remove the
file if it cannot be opened. This prevents the issue.

If `add_file` encounters a symlink it offloads the file addition to
`add_symlink`, and the link target to another `add_file`.
The first "file" is never added as a regular file, so do not mention
it in the verbose output. It will be mentioned by `add_symlink`.

  functions: use cp instead of stat+install in add_file when mode is not specified

See merge request archlinux/mkinitcpio/mkinitcpio!158

Tobias Powalowski authored Dec 02, 2022 and nl6720 committed Dec 03, 2022

`cp` alone is considerably faster than running `stat` (to get the permissions)
and copying the file with `install`.
This basically replaces calls to two external commands with one.
The directory of the target file is created by `add_dir` when using `cp`.

When the mode is specified, `install` is used as before.

Since add_udev_rule is available, there is no need to add the rule file with add_file.

cp will fail to copy `/` if the target directory already exists.
The produced error is not very helpful:

    cp: cannot create directory '/run/initramfs/': No such file or directory

Instead of copying `/`, copy `/.` to avoid the issue.

Fixes #104,
Fixes https://bugs.archlinux.org/task/74534

Revert "functions: try to avoid path traversal issues in add_file & add_binary by resolving the real path"

`realpath -s` is not guaranteed to return the **real path** in case
the path contains a symlink in it. E.g. `/usr/lib/symlink/../binary`.
Best not to work around potential edge cases of which no one has
complained about yet.

This reverts commit 3ecaccf3.

Some misconstructed hooks may set these variables globally and in case
they are not defined in vconsole.conf (and thus not overwritten), cause
errors when the consolefont, keymap or sd-vconsole hooks use the
incompatible values.
Setting them as local variables prevents this interference.

Fixes https://bugs.archlinux.org/task/76654

as workaround for FS#76468.

functions: remove special handling of relative symbolic links from add_file and simply use add_symlink

Now that add_symlink preserves relative symlinks, there is no need for add_file to copy the symlinks.
All symbolic link handling is now left to the add_symlink function.

Use find in place of readlink to return the symlink target just as it is and not the resolved absolute path.
This keeps relative symlinks relative.
