 mjm | and this is solving a pretty edge case in impermanence i think | 03:21:48 |
 ElvishJerricco | but sure | 03:21:49 |
| mjm | idk how i'd do it | 03:22:14 |
| mjm | i think this wouldn't be an issue for LUKS, since the decrypted FS has its own device and would show up separately from the encrypted one | 03:23:26 |
| ElvishJerricco | My first thought was to make a service for the directory you want to make that has RequiresMountsFor=/sysroot/persist/whatever and Before=/sysroot/bind/whatever that does the mkdir | 03:23:56 |
| ElvishJerricco | that way you don't have to make these assumptions they're making | 03:25:12 |
| mjm | yeah it's weird to me that they would mount it somewhere temporary instead of just introducing a service after /persist or whatever mounts and before the bind mounts | 03:26:23 |
| mjm | https://github.com/nix-community/impermanence/issues/222 if you feel like chiming in | 03:27:27 |
| ElvishJerricco | mjm: I mean frankly I think the problem that the service is trying to solve is a silly one | 03:28:47 |
| ElvishJerricco | like yes, you should make your directories | 03:28:54 |
| ElvishJerricco | it's weird that impermanence has to automated it for you | 03:29:07 |
| mjm | yeah, i think maybe it enables bootstrapping a system with impermanence from the get-go? idk i saw mention of nixos-anywhere in the PR that introduced it | 03:29:36 |
| mjm | but like, this hasn't been there for a while and i never noticed | 03:29:57 |
| mjm | so 🤷 | 03:30:06 |
| mjm | anyway, the fstab generator is pretty slick, excited to have it working! | 03:31:22 |
| ElvishJerricco | yea, thanks for testing! | 03:35:39 |

doesn't btrfs handle large numbers of snapshots absolutely terribly or something? The snapshots themselves are not so much the problem, it's mostly the combination with quota that causes the performance issues. | 12:56:08 |

 steveej | i'm trying to set up ipv6 prefix delegation with systemd-networkd on my router. i also run dnsmasq there and i'm not sure how relevant that is.
what i'm wondering is how i can confirm that my router is actually getting a delegated prefix from my ISP's router, or whether it just gets a single IP6 address | 09:35:49 |
| steveej | i believe i set all the necessary options on the router's WAN interface to accept RAs and also use dhcpv6 to ask for a delegated prefix. | 09:36:31 |
 K900 | ip a should show a prefix on the interface | 09:37:05 |
| K900 | If you're getting a prefix | 09:37:12 |
| steveej | do you mind showing me an example output for that? this is the wan interface output
4: wan@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
inet6 2001:XXX:9d94:4420:d4ac:76ff:fec0:7837/64 scope global dynamic mngtmpaddr noprefixroute
valid_lft 7149sec preferred_lft 3549sec
inet6 fdaa:XXX:ddee:0:d4ac:76ff:fec0:7837/64 scope global mngtmpaddr noprefixroute
valid_lft forever preferred_lft forever
inet6 fe80::d4ac:76ff:fec0:7837/64 scope link proto kernel_ll
valid_lft forever preferred_lft forever
slightly paranoid so i XXXd some values there
| 09:38:42 |
| K900 | You have a /64 | 09:39:17 |
| K900 | So yes that's a prefix | 09:39:21 |
| K900 | But normally you'd get a /56 from your ISP | 09:40:01 |
| K900 | For prefix delegation to work correctly | 09:40:05 |
| K900 | You can configure it to delegate smaller prefixes | 09:40:18 |
| K900 | But a typical setup would be to have a /48 or /56 for your router, and a /64 per device | 09:41:09 |
