Package: debianutils
Version: 2.15.1
Severity: important
File: /bin/which
Tags: patch
Hi,
On my system /bin/sh points to ksh, which doesn't provide the printf
builtin unlike bash does. So the /bin/which command calls /usr/bin/printf,
which may not be available at the boot time if /usr hasn't been mounted yet.
For the real time example of the bug see /etc/rcS.d/S30procps.sh script,
which calls `which' and runs just before the /etc/rcS.d/S35mountall.sh
I would suggest using good, old echo istead of printf. The attached patch
implements this.
Best regards,
robert
