fusermount and sleep undefined

[energizah]

https://github.com/nix-community/impermanence/blob/master/home-manager.nix#L92-L100 uses commands fusermount and sleep but they are not in scope, producing an error, Command not found.

That's odd, they should be put in the environment by https://github.com/nix-community/impermanence/blob/master/home-manager.nix#L122. sleep is in the coreutils package and the fusermount wrapper should be in /run/wrappers/bin by default. Do you have a more detailed log you can share?

Sure, here are logs from journald:

Based on the line numbers, it looks like you're using a pretty old commit. If so, can you try the latest and see if that solves the issue?

[energizah]

I think I'm on 2cda5cd . The errors are during stopScript, e.g. https://github.com/nix-community/impermanence/blob/master/home-manager.nix#L92

[talyz]

Note that writeShellScript adds an additional line at the top of the script, so the first line in the code would be line 2 of the resulting script.

If I run env -u PATH /nix/store/l6z18v8nd1bxyha2gnkzyncl7wpkfwb4-unmount-bindMount--persistent-home-talyz-Downloads-, built using the latest commit, I get the following output:

/nix/store/l6z18v8nd1bxyha2gnkzyncl7wpkfwb4-unmount-bindMount--persistent-home-talyz-Downloads-: line 5: fusermount: command not found
/nix/store/l6z18v8nd1bxyha2gnkzyncl7wpkfwb4-unmount-bindMount--persistent-home-talyz-Downloads-: line 13: sleep: command not found

The line numbers would have changed by +1 in b6181bd and then stayed the same, suggesting that you're on a commit prior to it.

Any news? Can we close this? :)

[energizah]

I haven't seen this in a while so I'll close.
