mountd suddenly stopped working

[Marcin Wisnicki]

I have just rebooted an old system after 100 days of uptime and this came
up:

Jun 30 15:39:00 ghost mountd[1592]: can't change attributes for /tftpboot
Jun 30 15:39:00 ghost mountd[1592]: bad exports list line /tftpboot     -ro -mapall


Both /etc/exports and /tftpboot are many years old and didn't cause any
problems until today.

I have tried fsck and rebooting but it didn't help.
