I had read around and found comments that it can actually make things faster and so I decided to give it a try.Could you, please, recompile both the kernel and reiser4progs (and possibly their dependencies :D) with -O2 instead of -O3 in CFLAGS? It tends to break things in strange and nasty ways, why do you have it enabled globally like this? Are you sure it's actually needed?
You said "break things in strange and nasty ways":Does this mean it can compile well and then just not WORK right (like for example: mkfs.reiser4 doing the wrong things when formatting)?? I only heard that it can break the compilation, no? And for me everything compiled fine.
The difference between -O2 and -O3 are these 6 options: > -fgcse-after-reload [enabled] > -finline-functions [enabled] > -fipa-cp-clone [enabled] > -fpredictive-commoning [enabled] > -ftree-vectorize [enabled] > -funswitch-loops [enabled] Can you maybe comment on them? ... Because I could also use O2 and turn on some of them...I was told: -ftree-vectorize and -funswitch-loops should be good and maybe -fpredictive-commoning?!
Also, CCache is not used anymore, remove it from FEATURES. If you actually _use_ CCache (i.e. you've installed it manually), unmerge it immediately. It's broken by design. Other stuff in your FEATURES looks fishy as well, but it shouldn't affect builds. I hope you know what you're doing.
Thanks! I used your comment to review my features again :) ... and I disabled CCACHE.If you don't mind: Now I am interested in your feedback about the other features:
These should be 100% secure, right:buildsyspkg -- secure I guess ;) ... and I like it in case something f's up big-scale in portage and I start emerging ;) ... happened once to a friend of mine ... just try to use portage when python is broken ;)
collision-protect -- useful I find
parallel-fetch -- faster downloads who doen't want that
metadata-transfer -- necessary for sqlite with portage (afaik)
noauto -- convenient
noinfo -- I just don't use "info"
SECURITY - Drop-Priviledges
--> should if things compile also be fine, right?
userpriv usersandbox userfetch usersync
SECURITY - MISC:
--> These I like for some additional (security) checking:
(I guess about them and the File-Permissions I am the most interested in
your opinion)
sandbox - seems also useful to me, no? strict - seems like a good thing from the description SECURITY - File-Permissions <<< they might be scetchy, right?... but should not do /harm/ sfperms suidctl Thanks a lot! Knuth
