The "Ex" variant was originally only added for ExecStartXYZ= but it makes
sense to have feature parity for the rest of the exec command properties
as well (e.g. ExecReload=, ExecStop=, etc).
It is natural that n_attiributes is less than type. But in that case,
the message does not contain any message about the type. So, we should
not abort execution with assertion, but just return -ENODATA.
"wall" was always NULL when passed to parse_password() so let's simplify this
part a bit.
The effective changes are small but wall_tty_match() needed to be moved so it's
still visible from parse_password().
No functional changes.
Commit a1c111c2d1 wrongly replaced '!' with ':' when the message is
forwarded to wall(1).
Indeed in this case we are not requesting the user for providing a password but
instead we are simply displaying a message to suggest starting
tty-ask-password-agent for providing the password.
In various circumstances, overriding the kernel commandline can be inconvenient.
People have different bootloaders, and e.g. the grub config can be pretty scary.
grubby helps, but it isn't always available.
This option adds an alternative mechanism that can quite convenient on EFI
systems. cmdline settings have higher priority, because they can be (usually)
changed on the bootloader prompt.
$SYSTEMD_EFI_OPTIONS can be used to override, same as $SYSTEMD_PROC_CMDLINE.
I want to use efivars.[ch] in proc-cmdline.c, but most of the efivars stuff is
not needed in basic/. Move the file from shared/ to basic/, but then move back
most of the higher-level functions to the new shared/efi-loader.c file.
It if of course related to /proc/cmdline parsing, but is higher-level
functionality built on top of it. It should be in shared/ because it
is something to be used by pid1 and related utilities, not something for
level-level libraries.
This way less stuff needs to be in basic. Initially, I wanted to move all the
parts of cgroup-utils.[ch] that depend on efivars.[ch] to shared, because
efivars.[ch] is in shared/. Later on, I decide to split efivars.[ch], so the
move done in this patch is not necessary anymore. Nevertheless, it is still
valid on its own. If at some point we want to expose libbasic, it is better to
to not have stuff that belong in libshared there.
This avoid the use of the global variable.
Also rename cgroup_unified_update() to cgroup_unified_cached() and
cgroup_unified_flush() to cgroup_unified() to better reflect their new roles.
During the rework of unit file loading, commit e8630e6952 dropped the
initialization u->source_mtime. This had the bad side effect that generated
units always needed daemon reloading.
This function had two users (apart from tests), and both only used one
argument. And it seems likely that if we need to pass more directories,
either the _nulstr() or the _strv() form would be used. Let's simplify
the code.
Update logging a bit: drop logging of the pid, nowadays pid1 and journald
do a very good job of logging that. Always log about failure to open audit
fd, but at DEBUG_LEVEL if not important.
relabel_extra() relabels the descendants of directories listed in
relabel-extra.d, but doesn't relabel the files or directories
explicitly named there. This makes it impossible to use
relabel-extra.d to relabel the root of a filesystem. Fix by
relabeling the named items too.
