ebuild.py around line 850 does something like this (pseudocode): if userpriv in features and ccache in features: # do some other things chown ccache_dir to portage_uid, portage_gid chmod ccache_dir to 0775 if ccache_dir is not owned by portage_gid or perms are not at least 02070: chown ccache_dir to portage_uid, portage_gid chmod ccache_dir to 02770 chown -R cache_dir to portage_uid, portage_gid chmod -R cache_dir to g+rw The net effect of this is that portage will do a chown -R and chmod -R on it on every ebuild step if both userpriv and ccache are in FEATURES. This is silly. A consensus should be reached on: * if the CCACHE_DIR doesn't exist yet, with what permissions do we create it? should these initial permissions depend on userpriv? * on each emerge run, what are the minimal permissions that are enforced? Do these depend on userpriv? There's also a bunch of open bugs on ccache permission problems (like 16664, 22125, 33162 properly" href="show_bug.cgi?id=84062">bug 84062). Some testing of the chosen permissions wouldn't hurt :) I've worked around this for now by making the unconditional chmod/chown in the first "if" above only happen if the ccache dir doesn't exist yet. I'm not sure if this is the "right" fix. Reproducible: Always Steps to Reproduce: 1. install cvs HEAD portage 2. FEATURES="ccache userpriv" emerge portage Actual Results: lots of (slow) "*** Adjusting ccache permissions for portage user..." Expected Results: only done that permission adjustment once.
