Hello,

I noticed that at the time of rootfs creation symbolic links of the ipk files present in deploy/ipk. The problem what have it while creation of symbolic link it take the full path till that ipk and remove slashes and convert them into underscores. Use that as the name of the symbolic link. This make a very long file names. If we have very long path then name of the symlink exceed from max filename limits. And we get following error

Collected errors:
* file_link: unable to stat `/var/jenkins/workspace/mel_cedar-main/buildhost/amd-ubuntu14-32b/buildtype/iot/machine/mel-dra7xx-evm/build_mel-dra7xx-evm/tmp/work/mel_dra7xx_evm-mel-linux-gnueabi/console-image/1.0-r0/rootfs//var/cache/opkg/volatile/file:_var_jenkins_workspace_mel_cedar-main_buildhost_amd-ubuntu14-32b_buildtype_iot_machine_mel-dra7xx-evm_build_mel-dra7xx-evm_tmp_deploy_ipk_mel_dra7xx_evm_kernel-module-lttng-ring-buffer-client-mmap-overwrite_2.6.2+git0+7a88f8b506-r0.0_mel_dra7xx_evm.ipk': File name too long.

Can anyone tell me why the addition of full path was added to the symlink name and can we remove it cause it is cause issues?

what does

getconf PATH_MAX /

show ?

jenkins at amd-ubu14-32-3:~$ getconf -a | grep  PATH_MAX
PATH_MAX                           4096
_POSIX_PATH_MAX                    4096


I think the issue is with file name not the path.

Secondly the googling which I did reveals that symlink creation can't be stopped. I just wanna confirm that is my findings correct?
