Du kan forl\u00e6nge leve tiden med at bruge noatime<\/strong> i \/etc\/fstab som vist her.<\/p>\n

# \/etc\/fstab: static file system information.\n#\n# Use 'blkid' to print the universally unique identifier for a\n# device; this may be used with UUID= as a more robust way to name devices\n# that works even if disks are added and removed.

fstrim<\/a> bruges p\u00e5 en monteret filsystem til at skille sig (eller “trimme”), blokke, der ikke er i brug af filsystemet. Dette er nyttigt for solid-state-drev (SSD’er) og tyndt klargjort opbevaring.
\nSom standard vil fstrim kassere alle ubrugte blokke i filsystemet. Optioner kan anvendes til at \u00e6ndre denne adf\u00e6rd baseret p\u00e5 r\u00e6kkevidde eller st\u00f8rrelse.<\/p>\n
