Right now that works because although you have _scratch_mkfs_sized using "$@" (doublequote-dollarsign-atsign-doublequote) to pass its arguments intact to _scratch_mkfs, it turns out that _scratch_mkfs just brazely passes $* (with no quoting) to the actual MKFS_PROG which results in any space in any single argument being treated as an argument separator and the string is broken into multiple arguments. This is why you *can't* do _scratch_mkfs -L "moo cow". This is also part of why everyone hates bash. --D > _scratch_xfs_db -c label > _scratch_xfs_admin -L newlabel "$@" >> $seqres.full > _scratch_xfs_db -c label > -- > 2.45.2 > >

To give the test option "-L oldlabel" to _scratch_mkfs_sized, xfs/157 does: MKFS_OPTIONS="-L oldlabel $MKFS_OPTIONS" _scratch_mkfs_sized $fs_size but the _scratch_mkfs_sized trys to keep the $fs_size, when mkfs fails with incompatible $MKFS_OPTIONS options, likes this: ** mkfs failed with extra mkfs options added to "-L oldlabel -m rmapbt=1" by test 157 ** ** attempting to mkfs using only test 157 options: -d size=524288000 -b size=4096 ** but the "-L oldlabel" is necessary, we shouldn't drop it. To avoid that, we give the "-L oldlabel" to _scratch_mkfs_sized through function parameters, not through global MKFS_OPTIONS.
