What you guys described, how do namespaces make any of that easier to implement than chroot?

"Easier" is actually the answer.  Yes, you can do the same thing with chroot + network namespace + cgroups + whatever, and then manually set up the OS image and hook things together etc.

LXC sets it all up for you, including the OS install, with one command.  If you want to do it the hard way, no one is stopping you.

Let me give you an example.  Over in the Citadel Support room someone is saying that an install fails on a particular Linux distribution on an ARM board.  I don't have that one.  But I can spin up an LXC of that distribution on my NanoPi and run the exact test, replicate the results, write a fix or a workaround, and blow it away.  Just like a virtual machine but in a fraction of the time.  If I tried that with chroot I almost certainly would not replicate the correct environment.

so, is minix development dead at this point?

I will take it one step further: is Andy Tannenbaum dead at this point or is he still kicking around telling us that microkernels are the only way to go?

He wanted Minix to be a teaching platform rather than a "real" OS.  He got his wish.  And he discovered that no one wanted a teaching platform OS any more than they wanted to write real software in LOGO.

Yes hes still around. Not sure if he is doing anything tho. Would be in his 80s. 

And it should not surprise you i support micro kernel concepts.

ouch, that xz issue even snuck into NetBSD pkgsrc   -> https://mail-index.netbsd.org/netbsd-announce/2024/03/30/msg000368.html

 

~~~~~~~~~~~~~~~~~~~~~

"Recently, a backdoor was discovered in the xz compression library.

xz/liblzma are included as a part of NetBSD and used by the project

for distribution of new releases and packages.

 

The version of xz shipped in all stable (and unstable) versions of

NetBSD predates any code changes by the author of the backdoor.

NetBSD is therefore safe and unaffected by the recent discoveries.

 

It is believed that the attack only targets Linux/glibc, but checking

this allowed us to rule out any other attempts at compromising the

library by the author.

 

The version of xz shipped in pkgsrc, however, is affected. Using

xz from pkgsrc is a non-default setting on NetBSD, and requires

explicit opt-in. Most users of NetBSD will not install xz from

pkgsrc because the version from the base system is preferred.

However, users of pkgsrc on other platforms will need to take

precautions.

 

Regardless of NetBSD being affected or not, the discovery of the

backdoor is a wake-up call and further discussion will be happening

internally over how to proceed.

While everything committed by that author is now suspect, the backdoor that's known specifically targets sshd as patched by Debian and RHEL to link with libsystemd (which is the circuitous way that liblzma winds up in sshd's program space). So, at least as far as is known for sure right now, simply having an xz with the change alone is beneign on non-systemd systems or unpatched sshds.

Have I mentioned lately that systemd sucks?

its a backdoor/virus all by itsself.
