freebsd-update in a jail

M

minimike

Hi there

I've installed FreeBSD 9 CURRENT on my Server because it gives me a better support about my hardware. On Jails I want to run FreeBSD 8.2-RELEASE. It runs fine, but I've got only one problem with freebsd-update on my jails.

Code: 
freebsd-one# freebsd-update -r 8.2-RELEASE upgrade
Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching public key from update4.FreeBSD.org... failed.
Fetching public key from update5.FreeBSD.org... failed.
Fetching public key from update3.FreeBSD.org... failed.
Fetching public key from update2.FreeBSD.org... failed.
No mirrors remaining, giving up.

Is there a trick to upgrade my 8.2-RELEASE based Jails?

cheers
Darko
 
Hi minimike,

Do you have an /etc/resolv.conf inside the jail? Why do you run upgrade? The jail is already 8.2-RELEASE, isn't it? What about freebsd-update -r 8.2-RELEASE fetch install?
 
Sorry! Do NOT run fetch install. Inside the Jail install does not work. You have to start freebsd-update -r 82.-RELEASE fetch and then chroot on the host: chroot /foo/bar/jail followed by freebsd-update install -> exit.
 
Hi! An identical problem.

Code:

freebsd-update only works on the host. I suggest you use the sysutil/qjail port to create and manage your jails. It has an update option to copy the host's running system files to the single basejail which is shared between all your jails. Very simple to use and has super documentation in the qjail man pages.
 
The ezjail option relying on freebsd-update does not work, it's a documented bug that has been waiting for two years to be fixed. The fix is that option has to be removed because freebsd-update is not jail-aware and just updates the host system. ezjail is outdated and has been replaced by qjail. All ezjail users should make the move to qjail.
 
I keep seeing mention of qjail in forum posts, but I never see any actual info about the port. I have no particular attachment to ezjail, but I'm not going to change all my servers to something else without good reason. Is there any comparison page out there or has anyone done a side-by-side of jail management apps? If there is a better tool out there I'd love to use it!
 
In this thread people have posted links to ezjail and qjail manpage. It don’t take a rocket scientist to see from just reading their manpages that qjail has progressed way beyond the functions provided by ezjail. Just give qjail a try and you will never look back at ezjail again. You will be happy you did.

True. I'll use qjail on new servers. Will keep ezjail on old servers for time being. Just do not want to change something which works fine at the moment.

How about ZFS support?
 
@fbsd1, maybe it would be a good thing to actually tell people that you are the qjail port maintainer, and therefore not entirely neutral on the subject. It's getting a bit evangelical at times. Maybe add it to your signature.
