Hello,
I'm trying to create a non-relocatable subpackage from a spec file, where
the
main package is relocatable, i.e. has a Prefix: tag. It is possible to use
Prefix:
for subpackages, e.g. to use a different value as for the main package, but I
have not been able to clear the main package's prefix setting. Using the
following
spec file:
Name: xxx
Version: 1.0
...
Prefix: /usr/local
%description
test
%package sub
Summary: subpackage
Prefix:
%description sub
subpackage test
...
(Prefix: without a value) generates the error message
error: line xx: Empty tag: Prefix:
Thanks in advance for any suggestions.
The real problem here is in the assumed goal of create a non-relocatable
subpackage.
Every path in every package can be relocated by --relocate /old/path=/newpath.
The
only restriction is that only full directory/file paths, not partial paths, can
be relocated.
E.g. given a path like /A/B/C/abc, one cannot relocate with a file prefix (or
pattern) like
--relocate /A/B/C/a=/somewhere/else
The only current usage for a Prefix: (and multiple Prefix:'s or Prefixes: are
permitted) is
to automatically disable a warning/error message that can be overridden by
another option.
If you want to use Prefix:, then specify all relocations in all subpackages.
The behavior
for a non-relocateable subpackage will always depend on what options were used
to install that package, and there is no way (nor should there be: only the
end-user,
not the builder, can determine what paths are useful/needed in general) to
prevent
--relocate from being used with appropriate overrides.
Note that the modestly serious design flaw with relocateable paths in *.rpm
packages is that
the relocations are not remembered persistently. So if you decide to relocate
some
path, then you also need to add --relocate on every future install.
The other flaw is that relocations are per-transaction (or CLI invocation), not
per-package.
This means that if you have two packages with an identical path which you want
to
relocate in one package but not the other, then the 2 package installations
MUST be
in in different transactions and installed separately.
