Commit e792e890f ("path-util: don't eat up ENOENT in
path_is_mount_point()") changed path_is_mount_point() so it doesn't hide
-ENOENT from its caller. This causes all boots to fail early in case
any of the mount points does not exist (for instance, when kdbus isn't
loaded, /sys/fs/kdbus is missing).
Fix this by returning 0 from mount_one() if path_is_mount_point()
returned -ENOENT.

Retrieve the handle to procfs in main(), and pass it functions
that need it. Kill the global variables.
Also, refactor lots of code in svg_title(). There's no need to access any
global variables from there either, and we really should return proper
errors from there as well.
Don't blindly exit() from random functions, but return a proper error
and upchain error conditions.
squash! bootchart: clean up control flow logic
When pread() returns "0", it's a read failure, so don't make the caller think
log_sample() was successful, return meaningful error code instead of 0.
We support /var, /tmp and /var/tmp on NFS. NFS shares however are by
default ordered only before remote-fs.target which is a late-boot
service. /var, /tmp, /var/tmp need to be around earlier though, hence
explicitly order them before basic.target.
Note that this change simply makes explicit what was implicit before,
since many early-boot services pulled in parts of /var anyway early.
- print runtime warnings with log_warning()
- save and restore $TZ properly
- Get rid of exit() pseudo error handling
- Using time() is OK when connecting to a local container or when
showing data about local host, but certainly not for remote hosts.
This provides equivalent functionality to libudev-device, but in the
systemd style. The public API only caters to creating sd_device objects
from for devices that already exist in /sys, there is no support for
listening for monitoring events or creating devices received over
the udev netlink protocol.
The private API contains the necessary functionality to make sd-device
a drop-in replacement for libudev-device, but which we would not
otherwise want to export.
