Hi,
ok - please don't laugh.
I did something completely different...
I added the following to 'make.sh':
***SNIP*** diff --git a/make.sh b/make.sh index 922fc4b4c..212256ab1 100755 --- a/make.sh +++ b/make.sh @@ -662,6 +662,11 @@ execute() { # If unshare is asked to terminate, terminate all child processes "--kill-child" )
+mount --bind ${BUILD_DIR}/proc ${BUILD_DIR}/proc
+mount --make-rslave ${BUILD_DIR}/proc
fi
I don’t know why this would fix anything.
I don't know either. If I remove these lines, I get the 'invalid argument' errors again. Immediately.
Could you once again try to swap the slave/private parameters of the —-propagation option for both calls of unshare?
Ok. I'll try and keep you informed, lets see. By the way: "Devel 1" just built 'next' in 3:09:49, updating 'rust 1.80.1' and 'clamav 1.4.0'.
1. I commented my two lines above and I get:
... Aug 16 16:34:12: Building stage2 unshare: cannot change /git/ipfire-2.x/build_x86_64/proc filesystem propagation: Invalid argument ...
2. I swap slave/private parameters => change line 646 to "--propagation=private" and line 2146 to "--propagation=slave" and get the same error: "...Invalid argument"
3. I swap parameters back and uncomment my two lines: => Build is running again.
Also: Why is this working on my freshly installed system?
Good question...this is something really strange...
while [ $# -gt 0 ]; do ***SNAP***
No 'invalid argument' error anymore.
I don't know why - but with this patch the build is running...
Any comments?

Hello,
We should not touch the mount propagation of the host’s namespace.
Instead, we should create our own mount namespace and that should be private.
You can however try to see what happens when you add —-propagation=slave to the first unshare command.
I just installed the plain Ubuntu Server, installed git, checkout out the repository, downloaded the toolchain and ran the build.

Hello Matthias,
Hi Michael,
just looked through https://man7.org/linux/man-pages/man1/unshare.1.html and ran 'findmnt -o+PROPAGATION' (see attachment).
I don't know if this could help but does this differ from your test installation?

Done.
Current state is as follows:
***SNIP*** ... root@Devel64-1: /git/ipfire-2.x # lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.4 LTS Release: 22.04 Codename: jammy ... root@Devel64-1: /git/ipfire-2.x # uname -mrs Linux 6.8.0-39-generic x86_64 ... ***SNAP***
But when I try to build 'next' I get exactly the same error as before:
***SNIP*** root@Devel64-1: /git/ipfire-2.x # ./make.sh build Packaged toolchain compilation Building IPFire stage2 Aug 2 21:21:15: Building stage2 unshare: cannot change /git/ipfire-2.x/build_x86_64/proc filesystem propagation: Invalid argument
Ah, this is good information. So it is not the kernel, it rather is Ubuntu handling something differently.
I will have a look at this and get back to you.

Being curious, I commented line line 633 in 'make.sh' ("--mount-proc=${BUILD_DIR}/proc") => Building starts but fails during 'glib 2.77.0':
