-Subject: [PATCH] Ticket #4180: fix zip handling.
-
-After 8857423e4ebb770b6f0ea3103abf5d35c85fcbe8 zip archives opened with
-an error:
-
- file -L -z archive.zip: Bad system call
-
-This caused by using /usr/bin/file with -z option, because seccomp (a
-security sandbox) doesn't allow it..
-
-Solution: use -S option together with -z one.
-
-The file command accepts the -S option since 5.33.
