Source: popularity-contest Version: 1.74 Severity: wishlist Tags: patch Dear Maintainer,
d/postinst hard-depends on bash to generate random days/hours/minutes; however, od -d -An -N2 /dev/urandom is equivalent to bash -c 'echo $RANDOM' ‒ patch 1 replaces the latter with the former; od is part of coreutils, and -d is a legacy switch so it's available on all implementations (and we already use it as a fallback for hostid generation). If we did -N1 we'd read only one byte, instead of 2, but that'd impact the distribution after mod, so I left that as-were. Patch 2 fixes remaining shellcheck annotations in d/postinst. Patches apply to current Salsa HEAD; I included gbp dch d/changelog output inside, as seems to be the custom. Feel free to drop it, of course.
