"mke2fs /dev/hda4"

That works, but might not be the most efficient use of space (lost space mainly from the *1 fid files which are very small VS a lot of space for inodes, considering that ~half the files are multiple megabytes large).

Ah, here are the mke2fs options the builder apparently uses: "-i131072 -m0 -s1" (128kBytes/inode, no reserved space for root/superuser, sparse super-blocks).
