+@JOURNAL_NAME@ (@JOURNAL_PATH@) сейчас занимает @CURRENT_USE_PRETTY@.
+Максимальный разрешенный размер составляет @MAX_USE_PRETTY@.
+Оставляем свободными как минимум @DISK_KEEP_FREE_PRETTY@ (сейчас на диске
+свободно @DISK_AVAILABLE_PRETTY@).
+Таким образом, предел использования составляет @LIMIT_PRETTY@, из которых
+@AVAILABLE_PRETTY@ пока свободно.
+
+Ограничения на размер журнала настраиваются при помощи параметров
+SystemMaxUse=, SystemKeepFree=, SystemMaxFileSize=, RuntimeMaxUse=,
+RuntimeKeepFree=, RuntimeMaxFileSize= в файле /etc/systemd/journald.conf.
+Более подробные сведения вы можете получить на справочной странице

+Служба разрешения имен хостов (systemd-resolved.service) определила, что

+
+Данное событие возникает, если в файле resolved.conf указан параметр

+путем отправки ложных сообщений от имени DNS-сервера.

-lookup3.c, by Bob Jenkins, May 2006, Public Domain.
-
-These are functions for producing 32-bit hashes for hash table lookup.
-hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final()
-are externally useful functions. Routines to test the hash are included
-if SELF_TEST is defined. You can use this free for any purpose. It's in
-the public domain. It has no warranty.
-
-You probably want to use hashlittle(). hashlittle() and hashbig()
-hash byte arrays. hashlittle() is faster than hashbig() on
-little-endian machines. Intel and AMD are little-endian machines.
-On second thought, you probably want hashlittle2(), which is identical to
-hashlittle() except it returns two 32-bit hashes for the price of one.
-You could implement hashbig2() if you wanted but I haven't bothered here.
-
-If you want to find a hash of, say, exactly 7 integers, do
- a = i1; b = i2; c = i3;
- mix(a,b,c);
- a += i4; b += i5; c += i6;
- mix(a,b,c);
- a += i7;
- final(a,b,c);
-then use c as the hash value. If you have a variable length array of
-4-byte integers to hash, use hashword(). If you have a byte array (like
-a character string), use hashlittle(). If you have several byte arrays, or
-a mix of things, see the comments above hashlittle().
-
-Why is this so big? I read 12 bytes at a time into 3 4-byte integers,
-then mix those integers. This is fast (you can do a lot more thorough
-mixing with 12*3 instructions on 3 integers than you can with 3 instructions
-on 1 byte), but shoehorning those bytes into integers efficiently is messy.

-mix -- mix 3 32-bit values reversibly.
-
-This is reversible, so any information in (a,b,c) before mix() is
-still in (a,b,c) after mix().
-
-If four pairs of (a,b,c) inputs are run through mix(), or through
-mix() in reverse, there are at least 32 bits of the output that
-are sometimes the same for one pair and different for another pair.
-This was tested for:
-* pairs that differed by one bit, by two bits, in any combination
- of top bits of (a,b,c), or in any combination of bottom bits of
- (a,b,c).
-* "differ" is defined as +, -, ^, or ~^. For + and -, I transformed
- the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
- is commonly produced by subtraction) look like a single 1-bit
- difference.
-* the base values were pseudorandom, all zero but one bit set, or
- all zero plus a counter that starts at zero.
-
-Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
-satisfy this are
- 4 6 8 16 19 4
- 9 15 3 18 27 15
- 14 9 3 7 17 3
-Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
-for "differ" defined as + with a one-bit base and a two-bit delta. I
-used http://burtleburtle.net/bob/hash/avalanche.html to choose
-the operations, constants, and arrangements of the variables.
-
-This does not achieve avalanche. There are input bits of (a,b,c)
-that fail to affect some output bits of (a,b,c), especially of a. The
-most thoroughly mixed value is c, but it doesn't really even achieve
-avalanche in c.
-
-This allows some parallelism. Read-after-writes are good at doubling
-the number of bits affected, so the goal of mixing pulls in the opposite
-direction as the goal of parallelism. I did what I could. Rotates
-seem to cost as much as shifts on every machine I could lay my hands
-on, and rotates are much kinder to the top and bottom bits, so I used
-rotates.

- initval : can be any 4-byte value
-Returns a 32-bit value. Every bit of the key affects every bit of

-totally different hash values.
-
-The best hash table sizes are powers of 2. There is no need to do
-mod a prime (mod is sooo slow!). If you need less than 32 bits,
-use a bitmask. For example, if you need only 10 bits, do
- h = (h & hashmask(10));
-In which case, the hash table should have hashsize(10) elements.
-
-If you are hashing n strings (uint8_t **)k, do it like this:
- for (i=0, h=0; i<n; ++i) h = hashlittle( k[i], len[i], h);
