What about DB corruption/loss? Do you keep the /var/db/pkg/<package>/xxx files even with pkgng and only use the DB as a way to speed up some work (so the DB corruption just requires to run pkg2ng), or are you lost of the DB is lost?
Nothing is done about DB corruption/loss, I am not sure we need to do something. Maybe.
I would say "for sure". Info: In Solaris 10 sqlite is used for the service managenemt framework (SMF). It is possible that the DB is corrupt in some bad situations. In this case you have to rebuild the DB (script provided, been there, had to use it).
If sqlite is properly used with transactions, it is very hard to corrupt the database. But if hardware lies to us and say that the
And as I told above, I even had such a case (more than once), and the hardware was not buggy. What do you want to tell in this case, "life sucks, reinstall everything"?
data is on disk whereas it isnt... what can we do?
Sometimes you have to stay with broken hardware.
Another potential problem is fsync(), but if it is broken on FreeBSD we want to fix it!
BTW, the goal is to only have the database and not the flat files. If you are paranoid about power outage, use something like zfs snapshots...
There are more FS than only ZFS (personally I use ZFS, and I have snapshots, but this is not a good solution for this problem).
As I told already, if it isn't automatic, nearly nobody will use it. And the package management stuff has to be automatic, no freshman will think about setting up a snapshot script when he starts to use packages/ports.
No need to look for strange scenarios, I'm surely going to sudo rm -f the file more sooner than later, so... maybe just save a copy?
A copy or two would be enough, but it has to be done automatically, and once a day is not enough. A copy after each X modifications maybe (for suitable definitions of X and 'modifications').
Bye, Alexander.
