Let's not leak details from src/shared and src/libsystemd into src/basic, even though you can't actually do anything useful with just forward declarations from src/shared. The sd-forward.h header is put in src/libsystemd/sd-common as we don't have a directory for shared internal headers for libsystemd yet. Let's also rename forward.h to basic-forward.h to keep things self-explanatory.

/* Typically, in places where one of the above specifier is to be resolved the other similar ones are to be

|
* resolved, too. Hence let's define common macros for the relevant array entries.
|
|
*
|
|
* COMMON_SYSTEM_SPECIFIERS:
|
|
* %a: the native userspace architecture
|
|
* %A: the OS image version, according to /etc/os-release
|
|
* %b: the boot ID of the running system
|
|
* %B: the OS build ID, according to /etc/os-release
|
|
* %H: the hostname of the running system
|
|
* %l: the short hostname of the running system
|
|
* %q: the 'pretty' hostname as per /etc/machine-info
|
|
* %m: the machine ID of the running system
|
|
* %M: the OS image ID, according to /etc/os-release
|
|
* %o: the OS ID according to /etc/os-release
|
|
* %v: the kernel version
|
|
* %w: the OS version ID, according to /etc/os-release
|
|
* %W: the OS variant ID, according to /etc/os-release
|
|
*
|
|
* COMMON_CREDS_SPECIFIERS:
|
|
* %g: the groupname of the running user
|
|
* %G: the GID of the running user
|
|
* %u: the username of the running user
|
|
* %U: the UID of the running user
|
|
*
|
|
* COMMON_TMP_SPECIFIERS:
|
|
* %T: the temporary directory (e.g. /tmp, or $TMPDIR, $TEMP, $TMP)
