Those of us running -release 7.8 (not -stable or -current)
may have noticed that anytime you reboot your machine the
next day you'll have a "daily insecurity output" email with
nothing but "Block device changes: /dev/rootdisk". You will
get this email anytime you reboot, every time.
Nothing is broke it's just /etc/rc creates the rootdisk
files every boot and /etc/daily sees the new timestamp.
But the emails can get annoying (WOLF!).
Before you start ignoring the insecurity emails you might
just want to add the following to /etc/rc.local
touch -r /dev/sd0a /dev/rrootdisk /dev/rootdisk
This will silence the false emails. /etc/rc still creates
the files as needed and you'll still get notified if the
rootdisk file does change and point to a new device.
No bug report filed as the developers have already fixed
it in current (/etc/rc only creates the files if changed).
But since this is just an "extra emails" issue there won't
be any patch for it to fix -release.
If you are more daring, grab a snapshot and copy "rc,v 1.587
2025/10/21" to replace the "rc,v 1.586 2025/09/17" included
in release 7.8. The only change is the rootdisk fix.
Now you'll get "Thou shall not change system files" emails.
