Description
$ strace -o /dev/null -e inject=/sigaction:error=EPERM true
fatal runtime error: assertion failed: signal(libc::SIGPIPE, handler) != libc::SIG_ERR, aborting
So uutils cannot be used under containers with restricted syscalls.
This looks coming from std: https://github.com/uutils/coreutils/blob/e9ad8b839c8243dfbb0476a3f2dcbc468565e8a3/src/uucore/src/lib/lib.rs#L150

Research direction
Start with src/uucore/src/lib/lib.rs around line 150 and reproduce the failure using the provided strace command. Trace which initialization paths and utilities depend on sigaction or poll, including dependencies from Rust std. Done means the affected utilities can be evaluated under restricted syscalls without the reported abort.
