2014-06-13sd-dhcp-server: bind to raw socket for sendingTom Gundersen
We would like to use the UDP socket, but we cannot as we need to specify the MAC address manually.
2014-06-13sd-dhcp-server: add basic message parsingTom Gundersen
Parse the maximum message size the client can accept and the client id, falling back to sane defaults if they are not set.
2014-06-13sd-dhcp-server: add basic message handling and verificationTom Gundersen
2014-06-13sd-dhcp-server: bind to a given interfaceTom Gundersen
We will (at least at first), restrict our focus to running the server on at most one interface.
2014-06-13sd-dhcp-server: add basic functionality for starting/stopping serverTom Gundersen
Bind to UDP socket and listen for messages, discarding anything we receive.
2014-06-13sd-dhcp-server: add basic functionality for creating/destroying server instanceTom Gundersen
2014-06-13dhcp-network: allow UDP socket to listen on any addressTom Gundersen
For this to work nicely we need to use REUSEADDR so that more than one socket can be open at the same time. Also, we request the ifindex to be appended to incoming messages, so we know whence it came.
2014-06-13tmpfiles: add minimal tmpfiles snippet to rebuild the most essential stuff ↵Lennart Poettering
from /etc
2014-06-13units: rebuild /etc/passwd, the udev hwdb and the journal catalog files on bootLennart Poettering
Only when necessary of course, nicely guarded with the new ConditionNeedsUpdate= condition we added.
2014-06-13core: add new ConditionNeedsUpdate= unit conditionLennart Poettering
This new condition allows checking whether /etc or /var are out-of-date relative to /usr. This is the counterpart for the update flag managed by systemd-update-done.service. Services that want to be started once after /usr got updated should use: [Unit] ConditionNeedsUpdate=/etc Before=systemd-update-done.service This makes sure that they are only run if /etc is out-of-date relative to /usr. And that it will be executed after systemd-update-done.service which is responsible for marking /etc up-to-date relative to the current /usr. ConditionNeedsUpdate= will also checks whether /etc is actually writable, and not trigger if it isn't, since no update is possible then.
2014-06-13update-done: add minimal tool to manage system updates for /etc and /var, if ↵Lennart Poettering
/usr has changed In order to support offline updates to /usr, we need to be able to run certain tasks on next boot-up to bring /etc and /var in line with the updated /usr. Hence, let's devise a mechanism how we can detect whether /etc or /var are not up-to-date with /usr anymore: we keep "touch files" in /etc/.updated and /var/.updated that are mtime-compared with /usr. This means: Whenever the vendor OS tree in /usr is updated, and any services that shall be executed at next boot shall be triggered, it is sufficient to update the mtime of /usr itself. At next boot, if /etc/.updated and/or /var/.updated is older than than /usr (or missing), we know we have to run the update tools once. After that is completed we need to update the mtime of these files to the one of /usr, to keep track that we made the necessary updates, and won't repeat them on next reboot. A subsequent commit adds a new ConditionNeedsUpdate= condition that allows checking on boot whether /etc or /var are outdated and need updating. This is an early step to allow booting up with an empty /etc, with automatic rebuilding of the necessary cache files or user databases therein, as well as supporting later updates of /usr that then propagate to /etc and /var again.

2014-06-13units: don't conditionalize sysctl serviceLennart Poettering
We install two sysctl snippets ourselves, hence the condition will always trigger, so no point in tryng to optimize things with this, it just will make things slower, if anything.
2014-06-13units: remove conditions from systemd-tmpfiles-setupLennart Poettering
There's no point in conditionalizing systemd-tmpfiles at boot, since we ship tmpfiles snippets ourselves, hence they will always trigger anyway. Also, there's no reason to pull in local-fs.target from the service, hence drop that.

2014-06-12sysuser: generate default snippet incorporating TTY_GID properlyLennart Poettering
When the user specifies --with-tty-gid= then we should honour that and write it to the snippet, too.

2014-06-12sysusers: add minimal tool to reconstruct /etc/passwd and /etc/group from ↵Lennart Poettering
static files systemd-sysusers is a tool to reconstruct /etc/passwd and /etc/group from static definition files that take a lot of inspiration from tmpfiles snippets. These snippets should carry information about system users only. To make sure it is not misused for normal users these snippets only allow configuring UID and gecos field for each user, but do not allow configuration of the home directory or shell, which is necessary for real login users. The purpose of this tool is to enable state-less systems that can populate /etc with the minimal files necessary, solely from static data in /usr. systemd-sysuser is additive only, and will never override existing users. This tool will create these files directly, and not via some user database abtsraction layer. This is appropriate as this tool is supposed to run really early at boot, and is only useful for creating system users, and system users cannot be stored in remote databases anyway. The tool is also useful to be invoked from RPM scriptlets, instead of useradd. This allows moving from imperative user descriptions in RPM to declarative descriptions. The UID/GID for a user/group to be created can either be chosen dynamic, or fixed, or be read from the owner of a file in the file system, in order to support reconstructing the correct IDs for files that shall be owned by them. This also adds a minimal user definition file, that should be sufficient for most basic systems. Distributions are expected to patch these files and augment the contents, for example with fixed UIDs for the users where that's necessary.

2014-06-11units: order network-online.target after network.targetLennart Poettering
There might be implementations around where the network-online logic might not talk to any network configuration service (and thus not have to wait for it), hence let's explicitly order network-online.target after network.target to avoid any ambiguities.

2014-06-11units: introduce network-pre.target as place to hook in firewallsLennart Poettering
network-pre.target is a passive target that should be pulled in by services that want to be executed before any network is configured (for example: firewall scrips). network-pre.target should be ordered before all network managemet services (but not be pulled in by them). network-pre.target should be order after all services that want to be executed before any network is configured (and be pulled in by them).

2014-06-11tmpfiles: when processing lines, always process prefixes before suffixesLennart Poettering
If two lines refer to paths that are suffix and prefix of each other, then always process the prefix first, the suffix second. In all other cases strictly process rules in the order they appear in the files. This makes creating /var/run as symlink to /run a lot more fun, since it is automatically created first.
