The init-file (files/laptop_mode.init) of app-laptop/laptop-mode-tools uses the bashism [[ ... ]] which breaks with baselayout-2. A simple solution is to replace [[ ... ]] by [ ... ] in that file.
this should be fixed in the init script for version 1.47
I waited some days to be absolute sure the new version has hit the mirror, but the crucial line 14 of the new init-script is still the same ([[ .... ]] instead of [ ... ]). So I am afraid that I have to re-open the bug. (I have to add to the original report: ...it breaks if e.g. /bin/sh is a symlink to dash, because [[ ... ]] is not POSIX-conformal as required by baselayout-2).
fixed in -r1
