 |
|
I'm doing an emerge which takes a long time to complete. In the meantime I like to emerge another application. When this application is finished I got a message that N config files need to be updated. But these are the config files from the other emerge still running. Is this a problem?
I always do it actually, but I'm not quite sure if it can't do any harm to the consistancy of my system.
EDIT: Sorry, I didn't search. There a few threads that I should read first  |

i think this has the possibility to screw up your system in some cases so its best to avoid it...
having said that - i do this all the time and i've never had a problem but mayb im lucky

My impression is that there isn't a problem unless two emerge processes try to perform the same step (writing to the portage database, say) at the same time. Then there will be a problem.
I also do it, and believe it shouldn't be a problem to emerge a tiny dockapp while kdelibs compiles. But realize the potential risk. |

spawning another emerge session isn't going to to speed things up, on the contrary, it will slow things down.
also, it may be dangerous, as I doubt whether, by design, emerge can deal with such senario.
if you have multiple CPU's you may want to consider tweaking
MAKEOPTS in your /etc/make.conf file as follows
where x is the number of CPU's you have + 1
or if you like to overload your system, and stress it to the max by all means try:-
and do emerge openoffice
PS don't do -j1000 at home :-)
