Serenity lost. Insanity looms darkly. /etc/mtab Random behaviour. xfs/189 fails After a week passing. -SCRATCH_DEV on SCRATCH_MNT type xfs (ro,filestreams) +SCRATCH_DEV on SCRATCH_MNT type xfs (ro,relatime,attr2,filestreams,inode64,noquota) Confusion prevails. /proc/mounts can never give success. Anything but golden. ls -l /etc/mtab shows: lrwxrwxrwx 1 root root 12 May 8 16:05 /etc/mtab -> /proc/mounts symlink modified. Stealth. Deception. WTF? Ninjas go unseen. "git grep mtab". Yay! generic/235: sad SElinux hack. Remount context grot. Mount uses all options from /etc/mtab Kernel rejects mount. sed hacks /etc/mtab Symlink becomes file. Test frobulation. xfs/189 passes Randomness tamed. Double face-palm. Tears. Crack-inspired insanity. mount(8) needs fixing. Schizophrenia. /etc/mtab. Same thing. Test psychiatry. Hack, slash, glue, polish. xfs/189 fixed. Made shiny again.
