invalid format for MountPoint in WSL2

[rue-nsilverman]

The most recent version of goreleaser includes this module and I have encountered an error running goreleaser in wsl. I use Docker Desktop using the WSL engine which creates local mounts inside linux to windows paths. The exact error is:

invalid format for MountPoint: "2619 80 0:302 / /Docker/host rw,noatime - 9p drvfs rw,dirsync,aname=drvfs;path=C:\\Program Files\\Docker\\Docker\\resources;symlinkroot=/mnt/,mmap,access=client,msize=262144,trans=virtio"

I assume given the a quick scan over the code, that the way the mount line is split is breaking because of the weird spaces and double backspaces in the path option. The version I am using is 1.5.2 of this module.

I just encountered this exact same issue while using the latest version of goreleaser as well :(

I went to investigate a bit more and the root of the problem is Docker Desktop for Windows creating an invalid mountpoint in /proc/X/mountinfo. Reference: docker/for-win#13318

Automaxprocs is not the only software failing to parse the spaces in the path subfield in the options field.

The error only happens when Docker Desktop is integrated into the WSL distribution and running. If Docker Desktop is stopped, the mountpoint is unmounted and automaxprocs (and other parsing software) does not error anymore.

In other words, automaxprocs is actually parsing the mountinfo metafile correctly (as defined in the official kernel documentation) and is Docker Desktop who should fix this issue.

In the linked issue, there is a workaround: install Docker Desktop for Windows in a location without spaces, e.g. C:\Docker.

Should be fixed in v1.5.3 release
