Hi, i think i found documentation about effective storage of very small files in ext4: https://ext4.wiki.kernel.org/index.php/Ext4_Disk_Layout#Inline_Data https://unix.stackexchange.com/questions/197633/how-to-use-the-new-ext4-inline-data-feature-storing-data-directly-in-the-inode https://man7.org/linux/man-pages/man5/ext4.5.html
I am currently tinkering with restoring chattr(1) attribute flags from ISO 9660 to disk. But it will last a while until i get to the 'N' attribute, especially since it is only an indicator and restoring will probably need setxattr(2) rather than ioctl(FS_IOC_SETFLAGS), as the settable attribute flags do. Recording such attributes is much easier than restoring them. Especially 'i', 'C', and 'F' constitute semantic mine fields for a backup program. So reports about suitability of inline data in ext4 would be appreciated. Have a nice day :) Thomas
