Re: Riddled by debian-policy 8.1.1 about ldconfig (original) (raw)

What is meant by "DEBIAN/triggers" in policy manual and man 5 deb-triggers ? Is there supposed to be a "DEBIAN" directory under ./debian ?

Hi Thomas,

the DEBIAN directory is created in the process of building in binary packages. In the binary packages themselves, its contents become the contents of the control.tar.gz member. For a package "p", the file DEBIAN/triggers is installed in /var/lib/dpkg/info/p.triggers. You can find many real examples there. In particular, for libraries complying with the Policy, you will see that this file indeed "activate-noawait" the "ldconfig" trigger. For packages built using Debhelper, the triggers files is added by dh_makeshlibs, which explains why you can not see traces of it in the clean source package.

I hope it clarifies.

Have a nice day,
