starting weston using systemd on tty=1 query

[Vikas Patil]

Dear All,

I am working on to start weston on tty=1 using the systemd, however it
fails to start on boot-up. If I launch weston after bootup using
"systemd start weston" then it works but not with the bootup. If I use
tty=2 then it work on bootup. systemd version is 225.

Could you anyone explain why it fails with tty=1 on bootup and works
with tty=2? Is there anyway I can start it on tty=1? Is it fine if I
start it with tty=2?

Here are the log for failure:
