chezmoi apply: "chezmoi: invalid argument"

[avh4]

Describe the bug

I'm setting up chezmoi on a new computer. chezmoi init ssh://git@... succeeded, and chezmoi status and chezmoi diff show the correct, expected output. But chezmoi apply immediately dies with "chezmoi: invalid argument".

To reproduce

# Boot new computer and log in as non-root user
chezmoi init ssh://git@myserver/user/dotfiles.git
chezmoi apply

Expected behavior

chezmoi apply should succeed (or print a helpful error message if there is actually something wrong)

Output of command with the --verbose flag

Additional context

[twpayne]

The "invalid argument" error is likely occurring when chezmoi tries to open its persistent state file. This uses BoltDB, which requires a filesystem that supports locking.

What's the output of mount? Is there anything non-standard about your machine?

[avh4]

Ah, thanks, that solves it! I'm doing some trial runs of the install, and currently have /home mounted as a shared drive.

For reference, mount includes:

$ mount
...
staging-home on /home type 9p (rw,relatime,sync,dirsync,access=client,msize=16384,trans=virtio)

If I mount a different fs over ./config/chezmoi, then everything works :white_check_mark:

If the error had included something like "unable to acquire lock for ./config/chezmoi/chezmoistate.boltdb" that would have been helpful.
