Package: nocache
Version: 1.0-1
Severity: normal
Tags: patch
Dear Maintainer,
To be effective for all enabled arches (e.g. with i386 cp and amd64
lrzip, `nocache lrzip foo; nocache cp foo.lrz /path/to/`, nocache must
be multi-arch co-installable. It is currently not (either you have it
for i386 [and it is of no use for amd64], or you have it amd64 [and it
is of no use for i386]).
Attached (somewhat hackish) patch fixes this (splits nocache to `M-A:
foreign` main package containing binaries and wrapper script, and `M-A:
same` libnocache package [supposed to be co-installed for all enabled
architectures];
Alternative layout can be main `M-A: same` package containing
/usr/bin/nocache and /usr/lib/*/nocache/*, and split off /usr/bin/cache*
binaries to separate `M-A: foreign` package.
FIXME: only checked on linux; no idea if hurd/kfreebsd ld.so also
supports $LIB (and multi-arch).
