sorry if I'm repeating an error (just in case), but searching for that one is quite hard and revealed nothing in the forum...
testing with 3.0alpha6:
tce-load -w -i mysql.tcz
/tmp/tcloop/mysql.tcz/... instead of /tmp/tcloop/mysql/... will be setup, then additionally the startup script from usr/local/tce.installed/mysql will not start (maybe because mysql.tcz is not mysql?) I'm experiencing the same problem while trying to make a new extension and I'm especially regarding the rights for tce.installed and its files... can anybody verify this or is my tc messed up?
