Timestamp path gets created with primary group of user who invokes doas

[djmattyg007]

When I enable the persist keyword and run doas, /run/doas gets created with the user root and the group djmattyg007. The permissions are correct (0600), so my non-privileged user account doesn't have access to the directory. It just seems strange that the group on the directory wouldn't also be root.

This was not done as I thought there was a TOCTU between mkdir(2) and chown(2) and that extra steps would be required to make sure not to chown(2) a different directory or a symlink.

But thinking about it now, I don't think there would be a TOCTU issue.

• mkdir(2) would return an error if the directory already exists so that the chown(2) immediately after mkdir(2) without extra checks would be safe as I understand it currently.
• mkdir(2) would return an error if the directory it tries to create is a dangling symlink so that is also not a problem.

All in all, maybe this can be changed if its safe, but also does not really change anything effectively as the mode is already restrictive and checked every time the directory will be used.
