I have a small "rescue" system (16 MB) that I boot into RAM as ramdisk. The initrd disk that I am preparing needs to be formatted. I think ext4 will do fine, but obviously, it doesn't make any sense to use journal or other advanced ext4 features.
How can I create the most minimal ext4 filesystem?
- without journal
- without any lazy_init
- without any extended attributes
- without ACL without large files
- without resizing support
- without any unnecessary metadata
The most bare minimum filesystem possible?
