The boot check is fast if the filesystem is marked clean.
This is only true if it has been unmounted in normal operation
or at an orderly shutdown.
A filesystem mounted read-only is normally marked clean.
A filesystem mounted read/write will always need fsck
after a system crash.
fsck can only mark a filesystem clean when it is run on a
filesystem which is not mounted.
I have multi-terabyte filesystems holding music, video, or images which
only change once a month or less.
Those are marked read-only in /etc/fstab.
I mount -u -o rw when needed, then mount -u -o ro when I am done.
This does not work for /usr, /var, /home etc.
