This rearranges bootctl a bit, so that it uses the usual verbs parsing
routines, and automatically searches the ESP in /boot, /efi or /boot/efi, thus
increasing compatibility with mainstream distros that insist on /boot/efi.
This also adds minimal support for running bootctl in a container environment:
when run inside a container verification of the ESP via raw block device
access, trusting the container manager to mount the ESP correctly. Moreover,
EFI variables are not accessed when running in the container.

If the ESP is not mounted with "iocharset=ascii", but with "iocharset=utf8"
(which is for example the default in Debian), the file system becomes case
sensitive. This means that a file created as "FooBarBaz" cannot be accessed as
"foobarbaz" since those are then considered different files.
Moreover, a file created as "FooBar" can then also not be accessed as "foobar",
and it also prevents such a file from being created, as both would use the same
8.3 short name "FOOBAR".
Even though the UEFI specification [0] does give the canonical spelling for
the files mentioned above, not all implementations completely conform to that,
so it's possible that those files would already exist, but with a different
spelling, causing subtle bugs when scanning or modifying the ESP.
While the proper fix would of course be that everybody conformed to the
standard, we can work around this problem by just referencing the files by
their 8.3 short names, i.e. using upper case.

That function doesn't draw anything on it's own, just returns a string, which
sometimes is more than one character. Also remove "DRAW_" prefix from character
names, TREE_* and ARROW and BLACK_CIRCLE are unambigous on their own, don't
draw anything, and are always used as an argument to special_glyph().
Rename "DASH" to "MDASH", as there's more than one type of dash.

This should be handled fine now by .dir-locals.el, so need to carry that
stuff in every file.

There are more than enough to deserve their own .c file, hence move them
over.

string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.
|
|
This also allows us to drop build.h from a ton of files, hence do so.
Since we touched the #includes of those files, let's order them properly
according to CODING_STYLE.

Some places invoked fflush() directly with their own manual error
checking, let's unify all that by using fflush_and_check().
This also unifies the general error paths of fflush()+rename() file
writers.

If /etc/machine-id is missing (eg., gold images), we should not fail
installing sd-boot. This is a perfectly fine use-case and we should simply
skip installing the default loader config in that case.

sdboot was renamed to systemd-boot

Otherwise it will not show any error stored

Do not print garbage on non-EFI installations.

Use strjoina to avoid error handling, and openat to simplify things.
Some fixes on the way:
- ferror does not set errno, so the return value was wrong in some cases
- errors are propagated in more cases
- EFI/systemd was created, but EFI/systemd-boot was deleted
- something is always printed on error
- when checking the version, comparison was done against "systemd-bo" for some reason
- return value was converted from negative to EXIT_SUCCESS/EXIT_FAILURE twice,
resulting in EXIT_SUCCESS all the time

- Move to its own file rm-rf.c
- Change parameters into a single flags parameter
- Remove "honour sticky" logic, it's unused these days

We already call parse_argv() from main(), don't call it here again.

It probably is but check anyway to make coverity happy.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

What used to be gummiboot, was renamed sd-boot when it was merged into
systemd. Let's try to be a bit more consistent with the rest of systemd
and rename it again as follows:
The EFI bootloader is now called 'systemd-bootx64.efi', and its sources are in
'src/boot/efi/'. The drop-in directory where bootctl will find EFI loaders
is now /usr/lib/systemd/boot/efi/.

getopt is usually good at printing out a nice error message when
commandline options are invalid. It distinguishes between an unknown
option and a known option with a missing arg. It is better to let it
do its job and not use opterr=0 unless we actually want to suppress
messages. So remove opterr=0 in the few places where it wasn't really
useful.
When an error in options is encountered, we should not print a lengthy
help() and overwhelm the user, when we know precisely what is wrong
with the commandline. In addition, since help() prints to stdout, it
should not be used except when requested with -h or --help.
Also, simplify things here and there.

Among other things this makes sure we always expose a --version command
and show it in the help texts.

It currently says 'time settings', change that to 'boot settings'.
