Could you please send the full output after adding set -x after every line in try that containes #!/bin/sh (should be three of them)

Can you confirm that it worked before that commit?

Yes, it worked before that commit.

Hello, could you try again but remove the ‘set -m’ at line 98. and making sure the other two ‘set -x’ is set.

could you also try using the branch nested-mount?

hshh · Answer 4 · Thu Jun 29 2023 15:28:20 GMT+0800 (China Standard Time)

Tried to remove line 98 'set -m', not work.
branch nested-mount, Error: Failed to mount overlayfs normally, mergerfs or unionfs not found for /run, see /tmp/tmp.2HDGhcPeFv

% cat /tmp/tmp.2HDGhcPeFv
mount: /tmp/tmp.RqsG9C9s8e/temproot/run: wrong fs type, bad option, bad superblock on overlay, missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.

Tianyu (Eric) Zhu · Answer 5 · Thu Jun 29 2023 15:29:56 GMT+0800 (China Standard Time)

Could you please install mergerfs and then trying again

hshh · Answer 6 · Thu Jun 29 2023 15:36:22 GMT+0800 (China Standard Time)

There is no pre-compiled mergerfs for Arch.
After installed mergerfs, it works, branch nested-mount.

hshh · Answer 7 · Sat Jul 01 2023 00:47:19 GMT+0800 (China Standard Time)

I hope it can be run without mergerfs.

Tianyu (Eric) Zhu · Answer 8 · Sat Jul 01 2023 00:59:04 GMT+0800 (China Standard Time)

unionfs is also a workable alternative if that works for you, you can also now just pull from the main branch as nested-mount is now merged in.

Could you send the output of the mount command so we can see why we needed union/mergerfs.

Can you try pulling from the latest main and removing the exit 1 at line 147

hshh · Answer 11 · Sat Jul 01 2023 02:00:31 GMT+0800 (China Standard Time)

After remove exit 1 line, it can enter try mode. But there is some warning.

If you don't care about /sys and /run, it works.
