Description
Hi, uutils mainteners
we confirmed redirecting chcon --verbose output when a a file exist, that not require selinux to be reproducable just a to exist
as i confirmed in my test
relunsec@relunsec:~/software/coreutils/target/debug$ ./chcon --verbose a a > /dev/full
thread 'main' (36701) panicked at /rustc/d595fce01043347bf7f80e85b76dcc41b59a3e6e/library/std/src/io/stdio.rs:1166:9:
failed printing to stdout: No space left on device (os error 28)

Research direction
Start by reproducing the reported command, chcon --verbose a a > /dev/full, without requiring SELinux. Trace the chcon verbose-output path and locate existing tests for its output or error handling. Done means the existing-file case no longer panics when stdout reports ENOSPC, with relevant regression coverage.
