What were you trying to do?
Use "track" to check out the files on a workstation's local
disk.
What's wrong:
It gave me unexpected output, though nothing was wrong:

As you can see from the last shell example, the questionable files are
all root-only readable (why?), so it's not surprising that track run
as uid 10993 (dkk) couldn't compare checksums. However, when track
can read the files, it seems to be getting bogus checksums for the
root-only-read files in /srvd/. The file contents aren't a problem,
though:
------------
m33-222-8# sum {/srvd,}{/bin/{clri,halt,icheck,rzdisk,shutdown},/etc/{install_upgrade,ris}}
46165 24 /srvd/bin/clri
35455 28 /srvd/bin/halt
18569 32 /srvd/bin/icheck
45724 64 /srvd/bin/rzdisk
65137 92 /srvd/bin/shutdown
53214 2 /srvd/etc/install_upgrade
02764 19 /srvd/etc/ris
46165 24 /bin/clri
35455 28 /bin/halt
18569 32 /bin/icheck
45724 64 /bin/rzdisk
65137 92 /bin/shutdown
53214 2 /etc/install_upgrade
02764 19 /etc/ris
------------
What should have happened:
------------
m33-222-8# track -v -c
using /srvd/etc/athena/lib/slists/sys_rvd as subscription-list
using /srvd/etc/athena/lib/stats/sys_rvd as statfile
cleared lock /tmp/sys_rvd.started
