conf: don't load sourcedir during initstepslew and RTC init
|
||||
|
||||
If the reload sources command was received in the chronyd start-up
|
||||
sequence with initstepslew and/or RTC init (-s option), the sources
|
||||
loaded from sourcedirs caused a crash due to failed assertion after
|
||||
adding sources specified in the config.
|
||||
|
||||
Ignore the reload sources command until chronyd enters the normal
|
||||
operation mode.
