Chris,
There are a few issues with the current man-db setup:
1) the cache is not strictly necessary for operation of man(1);
2) mandb -c is quite slow with a large number of manpages (~20min on my
system)
3) generating the cache only during man-db postinstall doesn't help for
manpages updated or added between man-db releases.
Therefore, we need to discuss further how to best handle the man-db
cache. In the meantime, to help avoid user complaints, could you ship a
new release without the postinstall/preremove?

I agree. The indexing should be removed from the post install.

Yes, that seems a bit too heavy for the postinstall.

Chris,
I'm hoping you're just on vacation atm. Because of the continued user
complaints, I went ahead and released a -2 without the cache
postinstall/preremove. Some missing runtime deps have also been
reported and are fixed on sourceware. Please resync with the following
in order to avoid any regressions:
