Yes, as Pavel said, "remount-ro" is just what happens if the filesystem
encounters an error which presumably it hasn't, at this point. :)

Ethernet/Wifi not working with coreboot/seabios/me_cleaner on a Thinkpad x230

[Zoran Stojsavljevic]

John,

You should join Ancient Greek philosophers: Plato, Aristotle, Plutarch,
Archimedes... The last one would be great Linux programmer, if he lived in
Modern World.

This advice I gave (also) to lot of PEs in INTEL IOTG, while I was there...
Very handy advice. ;-)

Pavel,

Thank you very much for the insight.

I see what you are saying (I did not know that), that the first mount /
attributes came out initrd. It probably happens while dracut re-pivots
initrd's / to hard drive's /.

Anyway, it should be checked. It says: error, then it says that it
remounted sda1 with EXT4-fs as RO (I assume it is /). I do not see very
often this line in dmesg (but I see it as seldom occurrence), so it must be
some sort of race effect, or...?!

Thank you,
Zoran
