[Pkg-sysvinit-devel] Bug#770342: "dashism" in /etc/init.d/bootlogs ?

Package: initscripts
Version: 2.88dsf-57

If I migrate a LXContainer from Wheezy to Jessie (using
sysvinit-core), then it gets stuck at boot time.

ps -ef --forest shows:

Please note the "dmesg" run by the bootlogs service script.
This is the part that gets stuck. If I kill -9 it, then the
rest of the container boots fine.

/bin/sh is a symlink to bash. If I use dash instead, then the
problem is gone. Is there some kind of "dashism" here?

On the command line the "dmesg -s 524288" works fine for both
dash and bash.
