@steveej0:matrix.orgsteveejdoes anyone happen to know whether nixos works well on hetzner's physical ARM machines RX170 or RX220?15:28:47
@hexa:lossy.networkhexait does15:33:43
@hexa:lossy.networkhexawe have both machines in our nixos infra inventory15:33:54
@steveej0:matrix.orgsteveejthanks!15:36:40
@steveej0:matrix.orgsteveeji can't build mongodb on the biggest ARM VPS. maybe there's a smarter option than just a bigger machine, however it'd be a nice upgrade15:37:16

the mongodb-ce package is in the cache if that helps

@steveej0:matrix.orgsteveejthat's good to know. i'll take a look if that has all the features that i need for the tests i'm writing19:57:16

@steveej0:matrix.orgsteveejis anyone here interested in rootless nixos-containers?10:04:27
@elvishjerricco:matrix.orgElvishJerricco steveej: I definitely would be 10:05:26
@elvishjerricco:matrix.orgElvishJerricco

oh, wait a sec, from systemd-nspawn's man page section on unprivileged operation:

Only disk image based containers are supported (i.e. --image=). Directory based ones (i.e. --directory=) are not supported.

When running in unprivileged mode, some needed functionality is provided via systemd-mountfsd.service(8) and systemd-nsresourced.service(8).

that sucks

10:07:20
@elvishjerricco:matrix.orgElvishJerriccoand it's really weird because you wouldn't need mountfsd (and the authentication craziness it entails) if you did directory based containers10:10:22
@steveej0:matrix.orgsteveejmaybe the systemd folks are open to implementing the gap. i'd be surprised as there doesn't seem to be much demand for systemd-nspawn in general10:14:53
@elvishjerricco:matrix.orgElvishJerriccosystemd-nspawn and systemd-vmspawn were designed first and foremost as tools to test an OS with, not so much a proper containerization / virtualization framework10:16:16
@elvishjerricco:matrix.orgElvishJerriccoof course nspawn has evolved a lot since10:16:37
@elvishjerricco:matrix.orgElvishJerricco But yea I don't really understand why directory based nspawn isn't possible unprivileged. That really does seem like the easier thing to do unprivileged 10:17:46
@elvishjerricco:matrix.orgElvishJerriccoso I bet it just wasn't the priority of whoever implemented unprivileged operation so they didn't do it10:18:08
@magic_rb:matrix.redalder.orgmagic_rbWouldnt it be better to just use runc for this? I do use nspawn but like, runc exists10:18:48
@elvishjerricco:matrix.orgElvishJerriccowell, if you wanna rewrite the nixos containers system with runc then be my guest :)10:19:42
