Source: file
Version: 1:5.38-3
Severity: normal

As the subject says: in my environment with libseccomp-dev installed,
the resulting file package gets a dependency on libseccomp2.  And if I
install that, then I subsequently get strange errors while trying to
build src:binutils, which I eventually tracked down to:

$ fakeroot file /usr/bin/file
Bad system call
$

"fakeroot strace file /usr/bin/file" shows:

msgget(0x41c5ccd5, IPC_CREAT|0600)      = ?
+++ killed by SIGSYS +++
Bad system call (core dumped)

(It might also be relevant here that I am running the Debian
environment within a systemd-nspawn container which already applies
its own seccomp filters, and also that I am running on a locally built
kernel not an official Debian kernel - and also the host system is a
custom built system so my systemd-nspawn does not have Debian
patches.)

I would guess the easiest way to resolve this would be to add an
explicit "--disable-libseccomp" to the dh_auto_configure command.
(Which I would certainly prefer to having the source package
Build-Conflicts: libseccomp-dev.)
