Yeah, i followed that, the CHROOT is now fine 
except now i get the prctl SECBIT_NOROOT (Operation not permitted)
example
./xpbs-src pkg linux6.2 
ERROR: prctl SECBIT_NOROOT (Operation not permitted)

What does this mean? does this mean that the chroot has this option?
my pid has all capabilities, output of getpcaps =ep
or is this a process inside the chroot which is a void process?
I also tired XBPS_ALLOW_CHROOT_BREAKOUT=yes and ran as root
the result was also
ERROR: prctl SECBIT_NOROOT (Operation not permitted)
