Filesystem is XFS.
My test user:
{
users.users.test = {
isNormalUser = true;
home = "/home1/test";
};
}
I’ve set ACLs like so.
{
systemd.tmpfiles.rules = [
"A /home1/test - - - - user:caddy:rwx"
];
}
After which it is applied.
sudo getfacl /home1/test
getfacl: Removing leading '/' from absolute path names
# file: home1/test
# owner: test
# group: users
user::rwx
user:caddy:rwx
group::---
mask::rwx
other::---
But if I run nixos-rebuild switch again, I no longer have these permissions. And it seems that the mask has changed:
sudo getfacl /home1/test
getfacl: Removing leading '/' from absolute path names
# file: home1/test
# owner: test
# group: users
user::rwx
user:caddy:rwx #effective:---
group::---
mask::---
other::---
I’ve tried explicitly setting the mask, and after rebuilding it works again, but rebuild a 2nd time after and results are the same as above.
{
systemd.tmpfiles.rules = [
"A /home1/test - - - - user:caddy:rwx"
"A+ /home1/test - - - - m::rwx"
];
}
I’ve tried similar with activationScripts and setfacl but get the same results. Google isn’t much of help, there are multiple unresolved similar posts:
