13 I don't think there's a simple yes or no answer to this problem. And I
14 am sure there's a lot of people who had their troubles with re-emerging
15 an entire system.
17 I myself did never experience any severe troubles. Recently I set up a
18 new test-server for combined file-, print-, mail- and web-services. I
19 fiddled around with PAM, LDAP and other stuff and decided three times
20 over the testing period to run an emerge --newuse -e world. We're
21 talking here something like 180 packages including Samba, CUPS, Courier,
22 Apache, PHP, PostgreSQL and X. Maybe I was lucky but everything went
23 just fine.
25 I believe that the cleaner you're system is the better chances are that
26 your system will survive an emerge -e. What's a clean system for me: a
27 system that does not show any signs of misbehaviour and that carries -
28 if at all - just a minimum of unstable packages safely defined
29 in /etc/portage.
31 On the other hand: if we are talking here about a productive system in a
32 multi-user environment then "Never touch a running systems" rules by all
33 means! ;-)
