E667 Fsync failed
Trying to append /proc/cmdline
Using vim, I add what I need to the end of the line. Since it's read only, I exit with :wq! which gives me:
"/proc/cmdline" E667 Fsync failed
WARNING: Original file may be lost or damaged don't quit the editor until the file is successfully written!
Press ENTER or type command to continue
If I press enter, I see the line appended and the process starts all over with same results. If I just try to quit, with :!q I am able to, but the file reverts back to what it was.
Has anyone encountered this problem before? Or can write-only files simply not be changed? BTW, I am root when doing all this.
