Odd_Bloke | cjwatson: wgrant: When we `mount -t (overlay|overlayfs) ...` in a build, the appropriate kernel module is loaded (despite modprobe not being permitted). Will that module remain loaded for future builds on the host? | 16:33 |
---|---|---|
cjwatson | Odd_Bloke: On virtual builders, no; on non-virtual builders, yes. | 16:37 |
cjwatson | (Well, until the host is rebooted.) | 16:37 |
smoser | so virtual builders launch a new vm and build you inside a chroot | 16:40 |
cjwatson | Correct. | 16:40 |
smoser | and non-virtual builders just build you inside a chroot | 16:40 |
cjwatson | Again correct. | 16:40 |
smoser | ok, that makes sense. | 16:41 |
cjwatson | This is another of the large class of reasons we want to get away from non-virtual builders. | 16:41 |
smoser | yeah. | 16:42 |
smoser | an lxc container i guess would plug the loading of module by mount kernel call | 16:42 |
smoser | by denying the mount | 16:42 |
smoser | but we need that in lots of cases | 16:42 |
cjwatson | There's also very little benefit to using LXC for us given the now-preferred model of doing everything in a fresh VM anyway. | 16:43 |
smoser | true story | 16:58 |
