Hi Troy,
thanks for the fast response. I'll attach my current "work spec" and
a tiny patch. Besides the changes described here, the spec is also
an attempt to make it possible to build the ia32e kernel module from it.
I just built a working 1.2.13 client + module for ia32e with it :) but
it's definitely work in progress - I'm not sure I understood that
"redhat-fix.h" trick.

Fine. I didn't want to press for getting any (major) changes in for 3.0.4.

You could use something like "rxdebug $server -noconnections". The timeout
for this is 20 seconds, but there's a prominent "#define TIMEOUT 20" in
rxdebug.c, so I guess one could build a modified version for this purpose.
Alas, the *debug commands are broken on 64bit :-(

See the demo spec:
* For the fileserver, we have to do this in %install (after
dest/root.server has been copied):
# lwp fileserver
mv $RPM_BUILD_ROOT%{_prefix}/afs/bin/fileserver \
$RPM_BUILD_ROOT%{_prefix}/afs/bin/fileserver.pt
install -m 755 src/viced/fileserver \
$RPM_BUILD_ROOT%{_prefix}/afs/bin/fileserver.lwp
ln -s fileserver.pt $RPM_BUILD_ROOT%{_prefix}/afs/bin/fileserver
and change %{_prefix}/afs/bin/fileserver to
%{_prefix}/afs/bin/fileserver* in the server packages' %files section.
* For the extra configure options, we need to change these defines
# OpenAFS configuration options
%define enable_bitmap_later 0
%define enable_bos_restricted_mode 0
%define enable_fast_restart 0
into this:
# OpenAFS configuration options
%define enable_bitmap_later 1
%define enable_bos_restricted_mode 1
%define enable_bos_new_config 1
%define enable_fast_restart 1
%define enable_full_vos_listvol_switch 1
and in %build, add to the config_opts= statement accordingly:
config_opts="--enable-redhat-buildsys \
%if %{enable_bitmap_later}
--enable-bitmap-later \
%endif
%if %{enable_bos_restricted_mode}
--enable-bos-restricted-mode \
%endif
%if %{enable_fast_restart}
--enable-fast-restart \
%endif
%if %{enable_full_vos_listvol_switch}
--enable-full-vos-listvol-switch \
%endif
%if %{enable_bos_new_config}
--enable-bos-new-config \
%endif
--enable-transarc-paths"

Simply add it to the openafs-file-list:
#
# create filelist
#
grep -v "^#" >openafs-file-list <<EOF-openafs-file-list
%{_bindir}/afsmonitor
...
%{_bindir}/scout
%{_bindir}/sys
%{_bindir}/livesys <----------
%{_bindir}/tokens
...
%{_sbindir}/vos
EOF-openafs-file-list
And if you feel like it, replace sys with it entirely.

It's in the demo spec as well: Besides the tiny
Patch301: openafs-1.2.10-twiddle.patch
and an unconditional
%patch301 -p0
in %prep, it takes
%package debug
Summary: OpenAFS additional debugging utilities
Requires: openafs = %{PACKAGE_VERSION}
Group: Networking/Filesystems
%description debug
The AFS distributed filesystem. AFS is a distributed filesystem
allowing cross-platform sharing of files among multiple computers.
Facilities are provided for access control, authentication, backup and
administrative management.
This package provides additional tools useful for understanding and
debugging the client and server. It is completely optional.
plus this in %build:
# additional debugging tools
make -C src/venus twiddle
make -C src/venus whatfid
make -C src/tests dumptool
make -C src/tests afsdump_scan
plus this in %install:
# extra debugging tools
mkdir -p $RPM_BUILD_ROOT%{_prefix}/afs/debug
for i in \
src/viced/cbd \
src/viced/fsprobe \
src/viced/check_sysid \
src/auth/setkey \
src/fsprobe/fsprobe_test \
src/rxdebug/rxdumptrace \
src/venus/twiddle \
src/venus/whatfid \
src/venus/test/getinitparams \
src/tests/dumptool \
src/tests/afsdump_scan \
src/ubik/utst_client \
src/ubik/utst_server \
src/vlserver/cnvldb \
src/vlserver/vlclient \
src/ptserver/readgroup \
src/ptserver/readpwd \
src/ptserver/testpt \
src/ptserver/db_verify \
src/kauth/rebuild \
;do
install -p -m 755 $i $RPM_BUILD_ROOT%{_prefix}/afs/debug
done
plus a %files section:
%files debug
%defattr(-,root,root)
%{_prefix}/afs/debug
%{_prefix}/vice/etc/C
(the /usr/vice/etc/C/afszcm.cat is a message catalog needed for making
various kinds of dumps human readable).
Cheers,
Stephan
