Hi all,
I would like to know if it's possible to set capabilities whith setcap for a specific binary
inside buildroot's rootfs image ?
I created a user account on target and I want to be able to run a program that needs CAP_SYS_NICE.
From what I have seen, it would be possible only in the fakeroot since the fakeroot's script
start with "chown -R 0:0".
chown drop all capabilities.
It appears that setcap tool is not working in fakeroot.
So, I updated fakeroot to the latest version (1.20) to have the last commit:
https://alioth.debian.org/scm/browser.php?group_id=30001
Also, I'm not sure if I need a specific version of host-tar (1.27.1) to save capabilities.
Do you have any suggestions ?
Thanks,
