You could also suppress the warnings using the -q option, for example: mke2fs -Fq -t ext4 -O bigalloc,quota -b 4096 -C 131072 /tmp/foo.img 4G > > Futher, mke2fs has multiple instances where we print warnings to stderr, > > should we go and fix all of them as well? > > "stderr" meaning "standard error", I'd say that errors are anything that > prohibits the format from completing, and only errors should go there. Sure, I'll accept those changes. But adding -q will allow the test to pass using older versions of e2fsprogs, while still allowing stderr to go out the expected output. - Ted
