We only use prelink on glibc based systems but they do give slight improved runtime/boottime performance on kind of devices yocto project is used on. However it will be good to get some idea of what this saving is now a days before we disable it fully. its perhaps better to disable it for ppc alone so something like this USER_CLASSES_remove = "image-prelink" in qemuppc.conf would be limited > > https://bugzilla.yoctoproject.org/show_bug.cgi?id=14429 > > Signed-off-by: Alexander Kanavin > --- > meta-poky/conf/local.conf.sample | 3 +-- > 1 file changed, 1 insertion(+), 2 deletions(-) > > diff --git a/meta-poky/conf/local.conf.sample b/meta-poky/conf/local.conf.sample > index fb14379d28..1794126672 100644 > --- a/meta-poky/conf/local.conf.sample > +++ b/meta-poky/conf/local.conf.sample > @@ -148,8 +148,7 @@ EXTRA_IMAGE_FEATURES ?= "debug-tweaks" > # enable extra features.
