hey, i was going to say that! 8-)
You actually want to do that for several reasons. For example, if you
don't, you can't handle the '-l' flag and parallel checking properly.
I'm also not entirely sure i understand how '-o' works.
For instance, what if you want to check all file systems of type 'ffs'
with the option '-f' and all file systems of type 'msdos' with the
options '-f' and '-y'? (I guess an example in the Makefile would
work, if that's reasonable possible...)
If that example is not possible to do with the current implementation,
i'd suggest something like:
fsck [common options] [file systems] \
[-T type [fs options] [file systems]]
i.e. to preen all file systems with -y, you'd just do:
to do the example above you'd do:
fsck -T ffs -f -T msdos -f,-y
if no file system type for a FS is specified, it should be determined
via the disklabel, /etc/fstab, or a default (ffs, probably).
if no file systems are specified, that means all.
I suppose there are additions to this (e.g. a -t-like option) that
make sense, but it quickly gets hard to describe coherently. 8-)
