- [x] Rebase split-usr MR !4 (closed)

The MR for split-usr is now part of this MR and will be in the next release. pmOS is no longer doing the usr-merge downstream.

merge request in pmaports for mrtest reasons

Known issues:

#3

• 948/1591 systemd:test / test-time-util: parse_time uses strtoll wrong. I don't think strtoll is supposed to handle '.'.

#4

• 947/1591 systemd:test / test-parse-util broken, as locale is disabled... (parsing 0,5 with de_DE.UTF-8 doesn't work).

#5

• 758/1591 systemd:network / test-network and 1069/1591 systemd:test / test-hostname-util: expected HOST_NAME_MAX on musl longer than on glibc. should be safe, when glibc passes this test-suite, as the desired shortening works then.
• 1081/1591 systemd:test / test-locale-util: locale_is_installed("zz_ZZ") == 0 (still) expected musl behaviour

#7

• 986/1591 systemd:libsystemd / test-bus-error: sd_bus_error_set_errnof GNU-specific strerror_r can return a const string in bus_error_strerror. But GNU behaviour is expected by this testcase.
• 1048/1591 systemd:test / test-errno-util: STRERROR() is completly broken. Should have been different strings.

#8

• 1053/1591 systemd:test / test-fileio: fputs in write_string_stream_ts fails with EOF, but fputs doesn't set an errno. this is a systemd musl mistake.

#9 (closed)

• 1055/1591 systemd:test / test-fs-util: fcntl.h is different in musl than in glibc. hence if ((flags & O_ACCMODE) != O_RDONLY) fails.

#10

• 1057/1591 systemd:test / test-glob-util: GLOB_ALTDIRFUNC and gl_opendir isn't a thing on musl. this will only be fixable if the glob implenentation is changed in musl or overridden during building.

#11 (closed)

• 1098/1591 systemd:test / test-path-util: uses basename with const chars, which is a glibc-ism. systemd-upstream already deprecates such calls to "non-posix" basename.

not reproducable:

• 1590/1591 systemd:core / test-path
