Spent some time on Haiku's homegrown `strace`.
Previously:
open(0x5, "plaintext", 0x2042, 0x0) = 0x8000000f () (49 us)
map_file("libicuuc.so.66 mmap area", 0x7f04c2675228, 0x6, 0x1ababd0, 0x1, 0x0, true, 0x3, 0x0) = 0x329a0 () (108 us)
Now:
open(0x5, "plaintext", O_RDWR | O_NOTRAVERSE | O_CLOEXEC, 0x0) = 0x8000000f Operation not allowed (57 us)
map_file("libicuuc.so.66 mmap area", [0x0], B_RANDOMIZED_ANY_ADDRESS, 0x1ababd0, B_READ_AREA, 0x0, true, 0x3, 0x0) = 0x73e8 ([0x6392223000]) (135 us)

@waddlesplash is there a lineage with Linux strace? or maybe some "horizontal transfer"? I know Linux strace will show you flags and partial buffers and more
@2ck Other than the name and some concepts, no, there's no "lineage". Haiku's strace is fully native, the source code isn't derived from the Linux one in any way.
