... Reply-To: Hi All,
A couple of questions ... I have "ROOTBACKUP=1" in /etc/daily.local to replicate my root partition as described in the FAQ (https://www.openbsd.org/faq/faq14.html#altroot) I noticed after an update to a new snapshot via sysupgrade that the next daily output email contains many many fsck "UNREF FILE" errors (See the output included below). Is this expected, or is there some problem? Most or all of the files seem to be owned by me (robb) so I'm thinking that these errors may be related to files in /tmp ... Not sure why this occurs though? Second question: Also after an upgrade, the "daily insecurity output" contains a huge amount of setuid changes e.g. ... -r-xr-sr-x 1 root auth 21144 Nov 30 15:36:52 2023 /usr/bin/skeyinit -r-xr-sr-x 1 root auth 21144 Dec 19 08:35:26 2023 /usr/bin/skeyinit -r-xr-sr-x 1 root _sshagnt 440496 Nov 30 15:36:53 2023 /usr/bin/ssh-agent -r-xr-sr-x 1 root _sshagnt 443856 Dec 19 08:35:26 2023 /usr/bin/ssh-agent -r-sr-xr-x 1 root bin 19608 Nov 30 15:36:53 2023 /usr/bin/su -r-sr-xr-x 1 root bin 19608 Dec 19 08:35:27 2023 /usr/bin/su -r-xr-sr-x 1 root tty 17936 Nov 30 15:36:54 2023 /usr/bin/wall -r-xr-sr-x 1 root tty 17936 Dec 19 08:35:28 2023 /usr/bin/wall -r-xr-sr-x 1 root tty 14184 Nov 30 15:36:55 2023 /usr/bin/write -r-xr-sr-x 1 root tty 14184 Dec 19 08:35:28 2023 /usr/bin/write -r-xr-sr-x 4 root _token 21248 Nov 30 15:36:44 2023 /usr/libexec/auth/login_activ -r-xr-sr-x 4 root _token 21248 Dec 19 08:35:18 2023 /usr/libexec/auth/login_activ ... What actually changed then? Surely many or all of these files had the same permission bits before the upgrade? Maybe these files now have diffent inode numbers, after the upgrade? Why is each filename reported twice? Are these "old" and "new" values? Thanks in advance for any feedback! Cheers, Robb. Subject: mjoelnir daily output ...
