Hi Geoffroy.
To be fair enough I have to say that mksquashfs is not only the target.
I need to execute any command I want in the future against install_root
from *.ks script.
So from now on I have understanding that (please, correct me if I am wrong):
1. to execute something special from %post section inside *.ks file I have
to install this 'something' into bootstrap.
a) I can extend mic-bootstrap adding 'BuildRequires: XXX' to
mic-bootstrap.spec and rebuild the mic-bootstrap rpm
b) I can extend the line packages=mic-bootstrap-x86-arm in
/etc/mic/mic.conf configuration and install XXX rpm along with
mic-bootstrap.
2. there is no any chance to execute 'something' from *.ks against
install_root after all umounts have been done.
(%post --nochroot is executed against directory which contains many
bind and other mounts)
that's bad, because it is insane to tar/mksquasfs/whatever with /proc,
/sys or even /home.
3. there is one more section which is called %traceback, but according to
my shallow understanding it is not used at all.
what is the real purpose of this %traceback ? probably somebody knows.
