When there are a lot of split out journal files, we might run out of fds
quicker then we want. Hence: bump RLIMIT_NOFILE to 16K if possible.
Do these even for journalctl. On Fedora the soft RLIMIT_NOFILE is at 1K,
the hard at 4K by default for normal user processes, this code hence
bumps this up for users to 4K.

Given the write patterns on disk images, we better should turn COW off
for them. In particular as the file systems used inside the disk images
should do their own data integrity checks anyway and we don't need
multiple layers of it.
|
|
btrfs' COW logic results in heavily fragment journal files, which is
detrimental for perfomance. Hence, turn off COW for journal files as we
create them.
Turning off COW comes at the cost of data integrity guarantees, but this
should be acceptable, given that we do our own checksumming, and
generally have a pretty conservative write pattern.

connected terminal
So far, if we had no knowledge about the correct $TERM we defaulted to
v102, as a safe, conservative choice. However, the terminfo data for
vt102 is not aware of pageup/pagedown, which makes "less" much harder
work with than necessary. Setting vt220 allows them to work correctly.
"vt220" should be a sufficiently safe choice too, given that xterm,
gnome-terminal and the linux console all strive to implement vt220 as
baseline, already to pass pageup/pagedown correctly to apps.
Effectively, with this change "journalctl -e" run inside a
"systemd-nspawn" terminal will now run a pager where pageup/pagedown
works, which is quite an improvement of usability for containers.

The daemon requires the busname unit to operate, since it contains the
policy that allows it to acquire its service name.

In particular, don't patch the error number to EINVAL if 0, and don't
negate it.
(Also, add do {} while (false) around multi-line macro)

The original loop called fix_order() on each service immediately after
loading it, but fix_order() would reference other units which were not
loaded yet.
This resulted in bogus and unnecessary orderings based on the static
start priorities.
Therefore call load_sysv() for every init script when traversing them in
enumerate_sysv(). This ensures that all units are loaded when
fix_order() is called.

The module appears under the name "libnss_myhostname.so.2" in the file
system, hence let's link it up under that name.

Remove a number of incorrect links, and explain that "localhost" and
"gateway" are now resolved by it, too.

Let's introduce some syntactic sugar with iteration macros, and add
correct key increment calls.

The list of provided facility names as specified via Provides: in the
LSB header was originally implemented by adding those facilities to the
Names= property via unit_add_name().
In commit 95ed3294c632f5606327149f10cef1eb34422862 the internal SysV
support was replaced by a generator and support for parsing the Names=
option had been removed from the unit file parsing in v186.
As a result, Provides: for non-virtual facility was dropped when
introducing the sysv-generator.
Since quite a few SysV init scripts still use that functionality (at
least in distros like Debian which have a large body of SysV init
scripts), add back support by making those facility names available via
symlinks to the unit filename to ensure correct orderings between
SysV init scripts which use those facility names.

Our write pattern is quite awful for CoW file systems (btrfs...), as we
keep updating file parts in the beginning of the file. This results in
fragmented journal files. Hence: when rotating files, defragment them,
since at that point we know that no further write accesses will be made.

Return value is successful only if everything succeeded.

LOG_DEBUG is already a log level, there is no need to use LOG_PRI which
is for filtering out the facility.

This patch adds more detail to the description of how path escaping
operates and provides a pointer to the systemd-escape program. Either
would serve to answer the question raised in the bug report, so
hopefully this will allow it to be closed.
