Interesting. I see musl has been doing this truncation since 2011, but I guess the coreutils build picked up statvfs() since musl started returning f_type in it: https://git.musl-libc.org/cgit/musl/commit/src/stat/statvfs.c?id=7291c6c6 I suppose we could adjust m4/stat-prog.m4 in coreutils to avoid statvfs detection on musl It would be worth suggesting to the musl folks to avoid this truncation. thanks, Pádraig
