It's not silly, I can see where this might be very useful; but noatime is applied at the vfs level and not at the filesystem level, so putting the flag in the filesystem superblock on disk and propagating that back up to the vfs at mount time might require a bit of trickiness to get right & do cleanly, I'm not sure. I'll give it some thought. It may be simpler & quicker to just tell your auto-mount framework to mount certain devices, or labels, or uuids, or $WHATEVER with noatime i= f you can? Of course that configuration is local to a single machine, an= d doesn't travel with the drive... -Eric > Happy Christmas to you. > Lars >=20 > Lars T=C3=A4uber schrieb: >> Hallo developers! >> >> I just would like to ask for a feature request for the ext[234] file= systems. >> There are some usb-sticks used by me that are formated with ext2.
