No, or I do not understand what you mean. The bug we are sending this to, #388399, is still open and RC, and nothing was fixed. I was just describing the history of the font cache, in order to have an argument why a user-invariant font cache directory might be acceptable. But that's a different issue, not related to #388399, and I have already sent a mail to [EMAIL PROTECTED] to separate this out. The bug #388399 still persists, and so far it only manifests itself on three buildds for alpha, mips and mipsel, and no one else has been able to reproduce it. And I must say that it really sucks to exchange so many e-mails on the topic without any input from the people who actually could help. >> If the admin chooses to create an empty /tmp/texfonts hierarchy without >> write access for users that need the font cache, that's equivalent to >> him creating an empty /var/cache/fonts/... without users having write >> access, in the old setup.

You are right, and while that's not a problem in most cases (hardly any system except buildds and build chroots have users without writable home directories that use TeX, and obviously up to now no system had two of them), it is a bug.
