Before, bytes were written and read in native + machine order as exposed by the native libc __cpu_mask interface. + Now, little-endian order is always used (CPUs 0–7 are described by + bits 0–7 in byte 0, CPUs 8–15 are described by byte 1, and so on). + This change fixes D-Bus calls that cross endianness boundary. + + The presentation format used for CPUAffinity by systemctl show and + systemd-analyze dump is changed to present CPU indices instead of the + raw __cpu_mask bitmask. For example, CPUAffinity=0-1 would be shown + as CPUAffinity=03000000000000000000000000000… (on little-endian) or + CPUAffinity=00000000000000300000000000000… (on 64-bit big-endian), + and is now shown as CPUAffinity=0-1, matching the input format. The + maximum integer that will be printed in new format is 8191 (four + digits), while the old format always used a very long number (with + the length varying by architecture), so they can be unambiguously + distinguished. + * /usr/sbin/halt.local is no longer supported. Implementation in distributions was inconsistent and it seems this functionality was very rarely used. @@ -83,7 +101,7 @@ CHANGES WITH 243 in spe: * When a [Match] section in .link or .network file is empty (contains no match patterns), a warning will be emitted.
