Hi,
while i try something i saw that usr/local/tce.installed in the corepure64.gz (9.x) has root:root ownership ? Is not root:staff usually for that folder ?
$ zcat corepure64.gz | cpio -i -v -t -m -d > textfile && cat textfile | grep tce.installed
28154 blocks
drwxrwxr-x   2 root     root            0 Feb 26 18:56 usr/local/tce.installed
$ whoami
tc
regards
Halma
