i have a requirement. browsed to find solutions about it.
i am building a binary rpm.
inside the spec file. i will calculate the size of the file being packaged. and i want to store it inside the rpm package as an entry in rpm HEADER/STORE/ or as a RPM_CUSTOM_XXX variables...I want to use it during installation in %pre section..before installing the file inside the package i want to make sure destination holds the enough free space. otherwise fail the installatino (..this is just one requirement..i have other custom requirements).
is it possible to put some hardcoded(userdefined data) value inside the rpm package at build time and use it during installation in %pre section? if yes? how to do it.
