In the file /etc/sudoers you'll need stuff like this:

# User privilege specification
root    ALL=(ALL) ALL

# Uncomment to allow people in group wheel to run all commands
# %wheel        ALL=(ALL)       ALL

# Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

# Samples
# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users  localhost=/sbin/shutdown -h now


The first one permits root to do everything without using a password
(yes you can lock root out of commands with this). The second
(commented) entry would allow everyone in the group wheel to run
any command with but it requires a password. The 3rd one same
thing, no password. The fourth & fifth are explicit commands with
passwords (use NOPASSWD: ncherry for user ncherry in group users).
I think you'll find that much easier than anything else. Maybe
something like this:

# user ecs permit mount and umount
ecs	localhost = NOPASSWD: /sbin/mount /mnt/flashdev,/sbin/umount /mnt/flashdev

Sorry about the wrap on the ecs line.
