Hello!
I have a custom buildroot image, for a M54418 coldfire. It works fine
with uclibc-ng (1.0.50).
I wanted to enable the LD_DEBUG support, with SUPPORT_LD_DEBUG but the
init fails.
I am using init=/bin/bash.
When I do not enable the configuration, I have:
[ 5.800748] Run /bin/bash as init process
[ 5.800807] with arguments:
[ 5.800865] /bin/bash

[ 5.801011] TERM=linux
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
bash-5.2#
I added SUPPORT_LD_DEBUG_EARLY and here is the output:
