Previously Ubuntu was treated as being equivalent to Debian, but the two
distributions require different behaviour in certain places. This commit does
not change the behaviour of systemd on either distro but it creates a
framework for changes to be introduced by later commits.
The following previously meant "Target is Debian or Ubuntu".
* configure option "--with-distro=debian"
* C preprocessor symbol "TARGET_DEBIAN"
* Automake conditional "TARGET_DEBIAN"
After this commit, all of the above are redefined to mean "Target is Debian"
The following are introduced to mean "Target is Ubuntu".
* configure option "--with-distro=ubuntu"
* C preprocessor symbol "TARGET_UBUNTU"
* Automake conditional "TARGET_UBUNTU"
Most code written for Debian will also be applicable to Ubuntu. An extra
Automake conditional "TARGET_DEBIAN_OR_UBUNTU" is introduced to avoid
duplication of code that would otherwise occur.
This commit updates configure.ac, Makefile.am and distro-specific source files
in line with the above definitions.
Reduce number of exported symbols with -fvisibility=hidden by default,
this is safe as we're not generating and loadable library and our
binaries should have no exported symbol other than main(). This alone
reduces around 4kb per binary.
It will also request GCC to emit every function and data variable in
its own section, then request the linker to remove unused
sections. This reduces the size of utility tools
(/lib/systemd/systemd-*) by half or even more (in my system some
binaries went from 84kb to 32kb).
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).

Here is the updated patch with a fix for the labeling of /dev/autofs

It seems to work on my machine.
/proc/1/fd/20 system_u:system_r:system_dbusd_t:s0
/proc/1/fd/21 system_u:system_r:avahi_t:s0
And the AVC's seem to have dissapeared when a confined app trys to
connect to dbus or avahi.
If you run with this patch and selinux-policy-3.8.8-3.fc14.noarch
You should be able to boot in enforcing mode.
Allow passing --with switches for SysV init path, SysV rcN.d path,
DBus and syslog service names.
Also bail out if those are not passed and distro is other
Attached is a patch for slackware support. If you want it some other
way, let me know; I haven't used git before.
Slackware doesn't have gnome or vala, and I'm having some issues with
the vala programs in systemd. I installed the vala compiler, and the
configure script says I have everything required, but compilation
fails (log attached). Is there something I'm missing? I installed
systemd by commenting out the vala programs in Makefile.am.

In some cases, people will run autoreconf rather than bootstrap.sh, or
they will uninstall pkg-config. This is now detected properly rather
than relying on bootstrap.sh checking for us.
