2014-05-16path-util: add path_make_relative()Tanu Kaskinen
In user_dirs() in path-lookup.c, I want to replace this: symlink("../../../.config/systemd/user", data_home); with symlink(config_home, data_home); to avoid hardcoding .config when XDG_CONFIG_HOME is set. The problem is that config_home is an absolute path, and it's better to make the symlink relative. path_make_relative() is an utility function that converts an absolute path into a relative one.
2014-05-15Make systemctl --root look for files in the proper placesZbigniew Jędrzejewski-Szmek
Running systemctl enable/disable/set-default/... with the --root option under strace reveals that it accessed various files and directories in the main fs, and not underneath the specified root. This can lead to correct results only when the layout and configuration in the container are identical, which often is not the case. Fix this by adding the specified root to all file access operations. This patch does not handle some corner cases: symlinks which point outside of the specified root might be interpreted differently than they would be by the kernel if the specified root was the real root. But systemctl does not create such symlinks by itself, and I think this is enough of a corner case not to be worth the additional complexity of reimplementing link chasing in systemd. Also, simplify the code in a few places and remove an hypothetical memory leak on error.

2014-04-12path-util: also check for existence of binary when given absolute pathZbigniew Jędrzejewski-Szmek
In contrast to a filename-only argument, find_binary() did not actually check if an path exists, allowing the code to fail later on. This was OK, but it seems nicer to treat both paths identically. Also take advantage of path_make_absolute_cwd doing strdup() by itself if necessary to simplify.
2014-04-12fsck: Search for fsck.type in PATHMike Gilbert
Modifies find_binary() to accept NULL in the second argument. fsck.type lookup logic moved to new fsck_exists() function, with a test.
2014-02-14shared: include root when canonicalizing conf pathsMichael Marineau
The conf_files_list family accepts an alternate root path to prefix all directories in the list but path_strv_canonicalize_uniq doesn't use it. This results in the suspicious behavior of resolving directory symlinks based on the contents of / instead of the alternate root. This adds a prefix argument to path_strv_canonicalize which will now prepend the prefix, if given, to every path in the list. To avoid answering what a relative path means when called with a root prefix path_strv_canonicalize is now path_strv_canonicalize_absolute and only considers absolute paths. Fortunately all users of already call path_strv_canonicalize with a list of absolute paths.

2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.

2013-10-29path_check_timestamp: only keep the most recent timestampTom Gundersen
There is no point in keeping one timestamp for each directory, as we only ever care about the most recent one.

I want to use this from a bulitin in a subsequent patch.

2013-04-16path-util: unify code for detecting OS treesLennart Poettering
This also makes sure we always detect an OS tree the same way, by checking for /etc/os-release.
2013-02-11binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services ↵Lennart Poettering
that work on .d/ directories This unifies much of the logic behind them: - All four will now ofllow the rule that the earlier file and earlier assignment in the .d/ directories wins. Before, sysctl was the only outlier, where the later setting always won. - All four now support getopt() and --help on the command line. - All four can now handle specification of configuration file names on the command line to apply. The tools will automatically find them, and apply them. Previously only tmpfiles could do that. This is useful for %post scripts in RPMs and suchlike. - This fixes various error path issues in conf_files_list()

2013-02-06systemd: do not remove empty paths from unit lookup pathZbigniew Jędrzejewski-Szmek
The ability to start a new unit with 'systemctl start ...' should not depend on whether there are other units in the directory. Previously, an additional 'systemctl daemon-reload' would be necessary to tell systemd to update the list of unit lookup paths.
2012-12-17path-util: set pointer to null after calling free()Michal Sekletar
In cases where path_strv_canonicalize() returns NULL, strv_free() is called afterwards and it will call free() on pointers which were freed already in path_strv_canonicalize()
