Package: dash
Version: 0.5.7-1
Severity: serious
Hi!
dash relies, for it's test builtin that faccessat returns useable
values for X_OK when called from the root user. Unfortunately that's not
true on kfreebsd (and seemingly not required by POSIX, see
#640325). Could you please just use the alternate code path on kfreebsd
which appears to work as wanted.
Thanks
Christoph

So relying on this is actually a bug in dash? (and there's probably no
easy way to check how faccessat is behaving right?)
Thanks for your information!

Description:
ash - compatibility package for dash

Changes:
dash (0.5.7-2) unstable; urgency=high

* debian/diff/:
- 0004-BUILTIN-Fix-test-x-as-root...diff: new; teach "test -x"
as root not to return true for nonexecutable files on
platforms where faccessat() does return true in this case,
such as glibc-bsd in squeeze (thx Christoph Egger, closes:
#640334).
- 0005-SHELL-Disable-sh-c-...diff: back out the optimization
that makes dash -c "script" avoid a fork(). It caused
several packages to fail to build from source (thx Stéphane
Glondu, closes: #642922).
