Subject: [PATCH] units/serial-getty@.service: use the default RestartSec
|
||
|
|
|
||
|
|
For pluggable ttys such as USB serial devices, the getty is restarted
|
||
|
|
and exits in a loop until the remove event reaches systemd. Under
|
||
|
|
certain circumstances the restart loop can overload the system in a
|
||
|
|
way that prevents the remove event from reaching systemd for a long
|
||
|
|
time (e.g. at least several minutes on a small embedded system).
|
||
|
|
|
||
|
|
Use the default RestartSec to prevent the restart loop from
|
||
|
|
overloading the system. Serial gettys are interactive units, so
|
||
|
|
waiting an extra 100ms really doesn't make a difference anyways
|
||
|
|
compared to the time it takes the user to log in.
