Description mom040267 2015-07-21 15:40:58 UTC

Parts of my 10.1.2 system keep disappearing after reboot. When I change something on the disk (a file, or I install a port), it works fine - up until next reboot. After the reboot, with a very good chance, my changes are gone. For example, I just installed several ports, but after the reboot they all disappeared:

Comment 1 mom040267 2015-07-26 19:46:17 UTC

I had a similar situation, again:

1) I downloaded an openssl tarball;
2) I compiled  and installed it into /opt;
3) I recompiled my program with the new prefix pointing to /opt.
4) The I rebooted the system.

The result:

1) The newerly compiled program is there, with library path pointing to /opt/
2) /opt directory disappeared.
3) The directory where I compiled the openssl disappeared, too (~/c/tmp/openssl/openssl-1.0.2/).

Something is very wrong going on.

Comment 2 mom040267 2015-07-26 19:57:19 UTC

After investigation, I found that this is probably about the Update Manager in PC-BSD. In the background, it is finding and destroying the directories that update the openssl and libressl. That is a very dangerous and unpredictable feature, and it has to be removed. 

I turned off all automatic updates, but I think that the Update Manager as a whole must be totally removed from the system, it is itself behaves worser than any security bug.

Comment 3 mom040267 2015-07-26 20:09:42 UTC

OK, I made an inventory of the damage. The "automatically" removed disk information is:

1) libressl is "automatically" downgraded from version 2.2.1 to 2.1.7 in /usr/local;
2) /opt directory with openssl 1.0.2d removed altogether;
3) All ports that were installed after libressl upgrade stopped working - because they were relying on libressl 2.2.1.

That's an increadicly stupid behavior of the Updated Manager, that's just unbelievable. The workaround is turning it completely off - but a novice unsuspected user may spend several days trying to find out what is really wrong with the system. That's very user-unfriendly and dangerous.

Hi.
If you need to file a bug report against PC-BSD, see https://bugs.pcbsd.org/projects/pcbsd for their bug tracker.

Since this feature is only in PC-BSD, not the base FreeSBD, you will need to open a ticket with them as mentioned.  Sorry for the inconvenience.

Comment 6 mom040267 2015-07-27 07:05:32 UTC

Thanks, I'll contact PC-BSD.

Hardware updated to 'amd64' as that is probably intended based on context.
