how to see boot messages when in a diagnostic shell?
Hi, all -- I am building a Leap 15.2 system and had some filesystem mount issues that caused the system to stick at "enter root password or press Ctrl-D to continue" asking for help. I did get that one (user missing from the passwd file but specified as an NTFS volume content owner) figured out, but it wasn't because I could figure out how to see the errors that went by before the screen cleared and the message & password prompt popped up. I tried looking in /var/log/messages and running dmesg and poking at anything else that I could imagine, but I never did see that mount error. When I'm in a recovery/maintenance single-user shell after a boot failure, how do I see the boot messages to read back and see what blew up? TIA & HAND :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt

When I'm in a recovery/maintenance single-user shell after a boot failure, how do I see the boot messages to read back and see what blew up?
Try "journalctl". Also: systemctl --failed to see what failed. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)

Ahhhhhhh ... OK. Now to remember that ... but it's a good pointer :-) % % Also: % % systemctl --failed % % to see what failed. Indeed. Thanks!

Yes, this is a command you must remember.
% % Also: % % systemctl --failed % % to see what failed.
Indeed. Thanks!
That one I had to look it up ;-) -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
