So, I think we need to port overlayfs to the new mount api because of https://github.com/util-linux/util-linux/issues/1992#issuecomment-1486475153 > > > A part of that is of course the support for idmapped mounts and the > > ability to recursively change mount properties, i.e., idempotently > > change the mount properties of a whole mount tree. > > > > It's also great to see support for disk sequence numbers via the > > BLKGETDISKSEQ ioctl and the port to util-linux to rely on > > BLKGETDISKSEQ is supported in the blockdev command only. > > Lennart has also idea to support it in libmount to verify devices > before the filesystem is attached to VFS. > > https://github.com/util-linux/util-linux/issues/1786 > > That's something we can work on in the next release. Yeah, I remember discussing that. Though that doesn't eliminate all races as we discussed on the thread and I plan to implement what I said in https://github.com/util-linux/util-linux/issues/1786#issuecomment-1410515391 rather soon and talked about at LSFMM last week. > > > statx(AT_STATX_DONT_SYNC|AT_NO_AUTOMOUNT) to avoid tripping over > > automounts or hung network filesystems as we just recently discussed > > this! > > > > Thanks for working on this and hopefully we can add the missing pieces > > of the new mount api in the coming months! > > I would like to make the v2.40 development cycle shorter.

I mean, after I did the initial support to get idmapped mounts working in there you still had to port all the rest of libmount...
