Subject: [PATCH 31/47] logind: use open_terminal() instead of open()
|
|
|
|
The open_terminal() function adds retries in case a terminal
|
|
is in the process of being closed when we open it, and should
|
|
generally be used to open a terminal. We especially need it
|
|
for code that a subsequent commit adds that reopens the terminal
|
|
at session shut-down time; such races would be more likely in
|
|
that case.
|
|
