Some more experimentation. This time limited to main, but across i386,
m68k, sparc, alpha and powerpc architectures. This doesn't reflect
whether packages in an architecture are up to date or not.
Statistics are:
i386 has 55 uninstallable packages -- 3494 total
alpha has 73 uninstallable packages -- 3246 total
sparc has 87 uninstallable packages -- 3191 total
m68k has 92 uninstallable packages -- 3205 total
powerpc has 100 uninstallable packages -- 3149 total
There are 201 distinct uninstallable packages all up, 3561 in total.
For interest's sake:
arm has 568 uninstallable packages -- 2003 total
hurd-i386 has 398 uninstallable packages -- 1033 total
Note that these are largely unverified.
I'm working on the basis that every package that can be built for an
architecture (ie, has Architecture: any, all, or includes whichever
architecture specifically) should be installable on that architecture.
Is that true?
libtricks gives me pause to wonder:
libtricks(1943) OKAY: [m68k, sparc, powerpc] BAD: [i386, alpha]
It's bad on i386 and alpha because libc6 conflicts with it. IIRC, it
got a little too friendly with libc's internal structure and hence died
when glibc2.1 came out. I'm not sure why sparc and powerpc don't also
have problems, though.
OTOH, m68k is still glibc2.0 based, so libtricks is fine there. How should
this be handled? By adding an `Architecture: m68k' ? But that's not very
accurate, it compiles fine on i386 if you've got glibc2.0. But on the
other hand, it doesn't seem like it should be included in Debian for
i386 or alpha because it's perfectly useless.
In this case, we've got an easy out, fakeroot works fine everywhere:
fakeroot(676) OKAY: [i386, m68k, sparc, alpha, powerpc]
But I wonder if, generally, it's reasonable to require all architectures
to make all packages available (neglecting minor things like packages with
i386-assembler, or whatever).
I'd like to think it is, but...
The list of which packages aren't installable on which architectures is at
http://azure.humbug.org.au/~aj/uninstallable_pkgs.txt
. It's 11kB or so, but probably not too exciting.
Cheers,
aj
