Yes, it's an issue with the initscripts (I'd say). I stumbled over this
problem as well when upgrading e2fsprogs on a fairly old Slackware install.
From the manpage of fsck:

The exit code returned by fsck is the sum of the following
0 - No errors
1 - File system errors corrected
2 - System should be rebooted

The old Slackware init scripts (from 7.0 days I think) checked

if [ $EXITCODE -gt 1 ] ; then

Newer fscks however also seem to return exit code 2 for "some errors
corrected, please reboot". In Slack 9's initscripts this was changed to auto
reboot in this case. I think this behaviour was changed in some version of
fsck, but I'm note sure.

But admittedly I also got a slight heart attack when our server stopped
booting with an error from fsck. ;)
