Description
Hi, uutils mainteners
we see when using --reference with /var/run/snapd.socket, no errors as out testing confirms
relunsec@relunsec:~/software/coreutils/target/debug$ ./truncate --reference /var/run/snapd.socket a
relunsec@relunsec:~/software/coreutils/target/debug$ echo $?
0
relunsec@relunsec:~/software/coreutils/target/debug$ gnutruncate --reference /var/run/snapd.socket a
gnutruncate: cannot get the size of '/var/run/snapd.socket': No such device or address
relunsec@relunsec:~/software/coreutils/target/debug$ echo $?
1
relunsec@relunsec:~/software/coreutils/target/debug$
as you can see the uu truncate no errors and exits with success, while the gnu one errors out to stderr and exits 1.

Start by reproducing the command shown with the Rust truncate binary and /var/run/snapd.socket, then inspect the truncate implementation and its existing tests. Done means this reference case reports the failure on stderr and exits nonzero, matching GNU truncate.
