It's essential to system, as btrfs device scan is needed before mounting 
a multi-device btrfs, and btrfs check is a an fsck that may be needed to 
fix a broken btrfs /usr/ mount.

Else reiserfsck, e2fsck, fsck itself, and others, should be in /usr/sbin, 
not in /sbin/.

btrfs is the general userspace binary.  Subcommands such as check and 
device scan require device privs and don't normally work when run as 
ordinary users, but some subcommands such as filesystem df don't need 
device privs and work just fine when run as ordinary users.

(Not that I particularly care about the topic of the thread in general, 
as here: /sbin -> bin, /usr -> ., so all four locations, /bin, /sbin,
/usr/bin, /usr/sbin, point to the same single /bin, and I no longer have 
to worry about which dir something's in, unless I'm checking the 
canonical path as installed by the package, for which equery belongs 
works nicely.  But I'm a btrs user and upstream btrfs list regular so I 
care about that angle, thus this reply. =:^)
