| 269 | <!-- EDITORS NOTE: Explanation on removing userdbd and homed:
|
|---|
| 270 | In BLFS, we do not fully support disk encryption. We offer instructions for
|
|---|
| 271 | building 'cryptsetup' as a dependency, but we do not offer instructions for
|
|---|
| 272 | actually configuring it. In addition, we generally do not include
|
|---|
| 273 | functionality that could potentially conflict with other packages, or that
|
|---|
| 274 | is not of any use to us (in an enterprise configuration using Thin Clients
|
|---|
| 275 | or laptops with LUKS encryption, it could make sense though, but that isn't
|
|---|
| 276 | the configuration that we natively support).
|
|---|
| 277 |
|
|---|
| 278 | A few of the complications of systemd-homed include:
|
|---|
| 279 | - SSH Logins
|
|---|
| 280 | - Disk Space Assignments
|
|---|
| 281 | - UID Assignments (chown() on login)
|
|---|
| 282 | (See https://cfp.all-systems-go.io/media/homed-asg2019.pdf)
|
|---|
| 283 |
|
|---|
| 284 | In an article I read when systemd-homed was originally unveiled, I remember
|
|---|
| 285 | reading about systemd-homed causing problems with OpenSSH Private Key Auth
|
|---|
| 286 | because the user would have to login at the console in order to unlock
|
|---|
| 287 | their home directory, thus allowing the private key to be unlocked and
|
|---|
| 288 | processed by OpenSSH. Since BLFS does not fully support encrypted disks,
|
|---|
| 289 | and because systemd-homed is incompatible with our usage of useradd /
|
|---|
| 290 | traditional UNIX users and groups, I advise that we take the following
|
|---|
| 291 | approach to avoid any confusion:
|
|---|
| 292 |
|
|---|
| 293 | - Leave the added Short Descriptions for homectl and userdbctl
|
|---|
| 294 | - Add the above command explanations and restore the previous behavior
|
|---|
| 295 |
|
|---|
| 296 | Should we decide to enable homed by default anytime in the future,
|
|---|
| 297 | let's move cryptsetup to recommended or required.
|
|---|
| 298 |
|
|---|
| 299 | I would be open to discussing this after the next systemd version when
|
|---|
| 300 | systemd-homed has matured a bit more. -renodr -->
