</span>On #2 I don't think you want to edit the package provided service file as that could get replaced with an update. I think you can copy it to /etc/systemd/service/ and make changes there... or at least I believe that's how it is supposed to work. I would think #1 would be a better solution.<br></blockquote><div>For now i'm doing masking on template creation ( <a href="https://github.com/CoolCold/openvz-tools/blob/master/templating/prep-jessie.sh#L94">https://github.com/CoolCold/openvz-tools/blob/master/templating/prep-jessie.sh#L94</a> ) , so using #1 <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

</span>I don't think so... but even if one is started, it shouldn't really use up much resources. I believe they are actually started on demand if and when one switches over to a virtual console.<br></blockquote><div>About resources:<br>root@ddiburatest:~# ps -eo 'rsz,command'|grep getty<br> 856 /sbin/agetty --noclear tty2 linux<br> 892 /sbin/agetty --noclear --keep-baud console 115200 38400 9600 vt102<br> 844 /sbin/agetty --noclear tty3 linux<br> 844 /sbin/agetty --noclear tty4 linux<br> 856 /sbin/agetty --noclear tty5 linux<br> 848 /sbin/agetty --noclear tty6 linux<br><br></div><div>so once instance is eating something like 900kb of RAM (resident size), though I don't see any difference from free -m output after stopping them. <br>about on demand: From what I see, it is not started on demand as A) there is no any switch to other virtual consoles by hand B) i've checked on VMware VM - and I clearly see it has been dynamically activated when i use alt+ctrl+f1/f2..<br></div><div>And anyway, it isn't needed, so why consume resources?<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
