Bug 177722 – sys-apps/baselayout: /etc/init.d/urandom script must respect size of random pool

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Yaroslav Isakov 2007-05-08 21:12:42 UTC]

Hello, recently I found the option to increase size of random pool in hardened-sources. But /etc/init.d/urandom doesn't respect this modification and saved only standard 4096 bits (it's 16384 with this option). So I modified /etc/init.d/urandom to be more flexible. Because I'm not a shell programmer, it needs sys-devel/bc (bash can do math internally, but I see that current policy is NO_BASH!, so bc dep).

ugh, dont use bc ... that isnt a required utility in Gentoo

just use shell to do math

Unfortunately, I know how to do this only with bash:
declare -i TMP_COUNT=$TMP_POOLSIZE/4096

TMP_COUNT=$((${TMP_POOLSIZE} / 4096))

Good enough, I've modified it a little more and it's in our svn trunk.
