[Bug]: Race condition in armbian-firstlogin
What happened?
armbian-firstlogin sometimes stucks without creating PRESET_USER_NAME due to ps|awk|kill race between multiple root sessions
How to reproduce?
I'm using BTT Pi board with the latest trixie minimal image Armbian_25.11.1_Bigtreetech-cb1_trixie_current_6.12.58_minimal.img

Maybe we should use flock binary from util-linux package to prevent these race conditions?
@schavkin Can you point to the racing executions?
I saved log for two cases: Successful case:

I had the same issue with my Radxa Cubie A7A build. I fixed this with short delay. Now tty1 has enough time to kill the other root sessions.

definitely not mergeable upstream, b/c there is also ttyS0 case [and possibly others, best to check /proc/cmdline].
We only need one root session to enter the preset information. The problem with the code is two root sessions login at the same time (tty1 and ttyS0). They both run the firstlogin script and execute the kill command at the same time. By delaying all root sessions except tty1 we solve the race condition. That’s what my snippet of code is effectively doing.
I wrote a script that has a priority list and the user can choose which tty fills in the preset information. In case tty1 is not used or they need ttyS0 to debug the preset information. https://github.com/NickAlilovic/build/commit/568ca704f846eb57847bbcb84046205efaffac31
