Gmane still has cygwin-apps read-only, so I hope it is acceptable if I post it
here until that is resolved... what I have implemented is to extract the list
of files to rebase into /etc/rebase/rebase_lst just like rebaseall would do.
Any extra files to rebase can be placed into list(s) in /etc/rebase/user.d (e.g.
perl5.10.1.lst as produced by perlrebase). Instead of rebuilding the whole list
every time, just extract from those package lists that are newer than the
rebase_lst. The update will be very fast even on systems which are struck by a
slow filesystem (in contrast to the initial build of the list, which is in
essence what the current autorebase script _always_ does).

rebase_lst () {
g="/etc/rebase/rebase_lst"
if [ ! -e "${g}" ]; then
touch -t 7001010000 /etc/rebase/rebase_lst
fi
for f in $( find /etc/setup -name '*.lst.gz' -newer ${g} ); do
echo "Updating rebase information from ${f} in ${g}."
cat >>"${g}" <<EOF

rebase_lst

The two directories in /etc and the /bin/rebaselst script are dropped in via a
package. In the installer script I then do something like that:
%CYGWIN_INST%\bin\ash -c "PATH=/bin cd /etc/rebase/user.d&&/bin/perlrebase"
%CYGWIN_INST%\bin\ash -c "PATH=/bin rebaselst"
%CYGWIN_INST%\bin\ash -c "PATH=/bin rebase -s -v -T /etc/rebase/rebase_lst"
I'll probably roll this into another script, but for now this seems to work
nicely enough.
Achim.
