When cross-compiling systemd, the introspection XML files fail to be
generated because the systemd host binary is not executable. This patch
works around this by putting the introspection XML data into separate
ELF sections and extracting them from the binary when generating the XML
files.
The extracted XML data is passed through the strings utility in order to
strip the trailing NUL character. A small AWK script is used to prepend
the doctype and add the opening and closing node tags respectively.
Finally, the C preprocessor is used to substitute the correct doctype
information from the D-Bus header files.
This patch adds a cpp definition HAVE_SYSV_COMPAT that is used to
isolate code dealing with /etc/init.d and /etc/rcN.d for systems where
it does not make sense (one that does not use sysv or one that is fully
systemd native).
The patch tries to be as little intrusive as possible, however in
order to minimize the number of #ifdef'ed regions I've reordered some
code in path-lookup.c:lookup_paths_init() where all code dealing with
sysv is now isolated under running_as == MANAGER_SYSTEM as well.
Moreover, In struct Service, some fields were rearranged to reduce
the number of ifdefs.
Lennart's suggestions were fixed and squashed with the original patch,
that was sent by Gustavo Sverzut Barbieri (barbieri@profusion.mobi).
