Great. Most users will use noatime anyway I guess, so it probably is not very important right now.

No, is asking to preserve access time of source. So mount with noatime or add O_NOATIME to open(2) call.

up !

I'm interested also in a feature like this : restore on an existing FS, or being able to specify FS creation flags.

I have some FS created a long time ago, when mkfs.ext3 didn't support 'resize_inode' (which permits online resizing). I since have migrated these FS on LVM volumes, and found that I couldn't grow my FS without unmounting them (which renders LVM less useful). The problem is that this flag can be set only on FS creation.

I tried all FS dumping utilities (partimage, partclone, fsarchiver, ...), but they all dump the whole FS structure, conserving flags from the old one. I thought that I could overcome this by using fsarchiver, dumping my ext3 FS and restore them in ext4, but in this case fsarchiver also creates an ext4 FS without 'resize_inode'.

Is a feature like this planned, or does anyone knows a save way to re-create my FS while preserving all files attributes ?

Thanks.
