Created attachment 697107 [details] strace of the file -z ./test.zip Result of the 'strace -f -v -e verbose=all -s 32768 -f -o ./strace.out file -z ./test.zip' command:
This is intentional by upstream although I agree it’s confusing. I’ve filed a bug upstream for better error handling (see linked bug). This is a bug in whatever application tried to use -z with seccomp if there was one. *** This bug has been marked as a duplicate of bug 771096 ***
Sorry, this one, on mobile. *** This bug has been marked as a duplicate of bug 776988 ***
Thanks, for the quick reply, Sam! Correct me if I'm wrong: a package that brought up an issue (because of upstream decision) is stable (sys-apps/file-5.39-r4), but the fixed version of the package it breaks is not stable (app-misc/mc-4.8.26-r2, ~amd64)?
