Unable to change owner/group of files using sshfs

[lcheylus]

I created a GH workflow with vmactions/openbsd-vm v1.0.4 to run a job (build of a Rust project on OpenBSD 7.4/stable).

I'm using sshfs to sync files between OpenBSD guest and Ubuntu host (GH runner): sync: sshfs

In a shell script used by my job on OpenBSD guest, I need to change owner/group of files using chown command.

Using the chown command, the run task fails:

Run 'run' in VM
/usr/bin/bash /home/runner/work/_actions/vmactions/openbsd-vm/v1.0.4/run.sh execSSHSH
  Config file: openbsd-7.4.conf

See my workflow logs https://github.com/lcheylus/cargo-nextest-openbsd/actions/runs/7428338886/job/20215523263 for details.

In run.sh script, sshfs runs with some options for files persmissions:

sshfs -o reconnect,ServerAliveCountMax=2,allow_other,default_permissions host:work $HOME/work

Is it possible to change these options to authorize to change owner/group of files from the guest ?

what is the option?

[lcheylus]

I don't know which options to change to fix this issue. It needs further tests between a Linux host and an OpenBSD VM with fuse/sshs.

[neilpang]

after the files are copied back to the Linux Host, you can use sudo to do anything.

[lcheylus]

With sshfs, files from OpenBSD VM are not copied back after end of job. Files between Linux host and OpenBSD guest are directly synced via a permanent SSH connection.

When I change permissions on OpenBSD VM with chown command, the errors occur because permissions are NOK on Linux host.

[neilpang]

so, don't run chown in the vm, just run it after the test in the Linux host.
