These are too much clutter. Move them to test directory until the test suite replacement is upstreamed.

This transparently supports curing foreign exec artifacts.

cmd/sharefs: reproduce vfs inode file attribute race2026-04-08T06:51:36ZOphestracat@gensokyo.uk2026-04-08T06:39:04Zurn:sha1:351d6c5a35adcf07ccfe62add266d5db540400ed
This happens in the vfs permissions check only and stale data appears to never reach userspace.

nix: configure sharefs via fileSystems2025-12-27T14:14:08ZOphestracat@gensokyo.uk2025-12-27T13:52:12Zurn:sha1:e42ea32dbe9283d14a7c0e8746059bc5ef97f6cd
Turns out this did not work because in the vm test harness, virtualisation.fileSystems completely and silently overrides fileSystems, causing its contents to not even be evaluated anymore. This is not documented as far as I can tell, and is not obvious by any stretch of the imagination. The current hack is cargo culted from nix-community/impermanence and hopefully lasts until this project fully replaces nix.

cmd/sharefs: create directory as root2025-12-27T13:14:33ZOphestracat@gensokyo.uk2025-12-27T13:09:55Zurn:sha1:e7982b4ee9cc935d6b89f291087524cdee229d09
This optional behaviour is required on NixOS as it is otherwise impossible to set this up: systemd.mounts breaks startup order somehow even though my unit looks identical to generated ones, fileSystems does not support any kind of initialisation or ordering other than against other mount points.

cmd/sharefs: containerise filesystem daemon2025-12-27T01:16:35ZOphestracat@gensokyo.uk2025-12-27T00:17:14Zurn:sha1:2f8ca8337633a199aae9b4cdd71c66ed1c9529a5
This replaces the forking daemonise libfuse function which prevents Go callbacks from calling into the runtime. This also enforces least privilege on the daemon process.

This allows unrestricted use of the type system and prepares setup code for cross-process initialisation.

This change should not change behaviour other than making output more consistent.

This verifies behaviour related to setuid/setgid when starting as root.

This is for passing files between applications, similar to android /sdcard.
