The init file /etc/init.d/lighttpd contains a line LIGHTTPD_PID="$($(which lighttpd) -pf ${LIGHTTPD_CONF} | grep pid | cut -d '=' -f 2 | tr -d \\\" | tr -d [:space:])" This line runs the lighttpd program with the -p flag to print parsed configuration. The problem is that when the filesystem is in read-only state, for example when booting, lighttpd -p hangs (I don't know if it wants to write somewhere or what...). Thus this command hangs. This file is called from /lib/rc/sh/gendepends.sh to get service dependencies, before setting the filesystem read-write, thus hanging the boot process of the whole system. As a result the system hangs on booting after writing the lice Caching service dependencies. I had to change the line to LIGHTTPD_PID="$(cat ${LIGHTTPD_CONF} | grep pid | cut -d '=' -f 2 | tr -d \\\" | tr -d [:space:])" to make it work.
Hi. I'm OK that change. We could even remove one shell spawn by avoiding calling cat: LIGHTTPD_PID="$(grep pid ${LIGHTTPD_CONF} | cut -d '=' -f 2 | tr -d \\\" | tr -d [:space:])" Could you try and report back? It should work as well. If it does, I'll commit the change straight away.

Ah, nice catch! The change looks good to me.
The improved version of the fix (monsieurp's) was added to the Gentoo repository. Re-sync and re-emerge lighttpd to receive the updated copy. Commit ID: 258e3475e0eda930f424d3141cb3ba9fc0f87a9a Thanks for reporting, Marek!
Thank for the fix! I looked at hangup issue today on virtual server. It hung for me because 'lighttpd -t' called 'getrandom()' which blocks unless random pool is initialized in kernel. As a result boot took 3 minutes. Openrc calls gendepend (and 'lighttpd -t' at top level) even before /etc/init.d/urandom is called. /etc/init.d/urandom is supposed to refill entropy pool after previous boot.
I also suggest revbumping ebuilds for users to pull init.d change sooner.
lighttpd 1.4.44 was released in Dec 2016 (the month following the discussion here) and deferred the call to li_rand_init(). That change in lighttpd 1.4.44 should have addressed the issue raised here. The change made here to LIGHTTPD_PID in /etc/init.d/lighttpd, should probably be reverted, as it has caused problems. See https://bugs.gentoo.org/626688, where I have referred back to this issue and suggested the same solution.
