Package: runit-init Version: 2.1.2-52 Severity: grave Justification: makes the system unbootable
Hi, in order to investigate runit-init as a possible init alternative, I tried booting a minimal Debian system containing runit-init and a linux kernel image. This is what I got: | Begin: Running /scripts/local-bottom ... done. | Begin: Running /scripts/init-bottom ... done. | [ 1.518637] Not activating Mandatory Access Control as /sbin/tomoyo-init does not exist. | - runit: $Id: 25da3b86f7bed4038b8a039d2f8e8c9bbcf0822b $: booting. | - runit: enter stage: /etc/runit/1 | /etc/rcS.d/S01mountkernfs.sh: 280: mount: not found | /etc/rcS.d/S01mountkernfs.sh: 280: mount: not found | /etc/rcS.d/S01mountkernfs.sh: 280: mount: not found | Starting hotplug events dispatcher: systemd-udevd. | Synthesizing the initial hotplug events (subsystems)...done. | Synthesizing the initial hotplug events (devices)...[ 1.752098] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 | done. | Waiting for /dev to be fully populated...[ 1.763554] sr 1:0:0:0: Attached scsi generic sg0 type 5 | [ 1.766920] ACPI: button: Power Button [PWRF] | [ 2.180257] RAPL PMU: API unit is 2^-32 Joules, 0 fixed counters, 10737418240 ms ovfl timer | [ 2.196663] cryptd: max_cpu_qlen set to 1000 | [ 2.284932] AVX2 version of gcm_enc/dec engaged. | [ 2.286968] AES CTR mode by8 optimization enabled | done. | /etc/rcS.d/S03mountdevsubfs.sh: 280: mount: not found | Activating swap...failed. | /etc/rcS.d/S04checkroot.sh: 210: mount: not found | Cannot check root file system because it is not mounted read-only. ... failed! | /etc/rcS.d/S04checkroot.sh: 316: mount: not found | Creating compatibility symlink from /etc/mtab to /proc/mounts. ...

The biggest problem here is the lack of mount. mount is not essential and nothing depends on it, so it goes missing. Something in the runit ecosystem should definitely depend on mount. Then after boot, no getty is spawned and there is no way to log in. I retried with mount installed and got something different: | Begin: Running /scripts/local-bottom ... done. | Begin: Running /scripts/init-bottom ... done. | [ 1.554225] Not activating Mandatory Access Control as /sbin/tomoyo-init does not exist. | - runit: $Id: 25da3b86f7bed4038b8a039d2f8e8c9bbcf0822b $: booting. | - runit: enter stage: /etc/runit/1 | Starting hotplug events dispatcher: systemd-udevd. | Synthesizing the initial hotplug events (subsystems)...done. | Synthesizing the initial hotplug events (devices)...done. | Waiting for /dev to be fully populated...[ 1.770569] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 | [ 1.783674] sr 1:0:0:0: Attached scsi generic sg0 type 5 | [ 1.796417] ACPI: button: Power Button [PWRF] | [ 2.151984] RAPL PMU: API unit is 2^-32 Joules, 0 fixed counters, 10737418240 ms ovfl timer | [ 2.155414] cryptd: max_cpu_qlen set to 1000 | [ 2.287889] AVX2 version of gcm_enc/dec engaged. | [ 2.290906] AES CTR mode by8 optimization enabled | done. | Activating swap...done. | [ 3.003917] EXT4-fs (vda): re-mounted.

Nowadays, checking ext4 filesystems is optional and systemd skips doing it in the absence of e2fsprogs. So I went on to retry with e2fsprogs added and this is what I got: | Begin: Running /scripts/local-bottom ... done. | Begin: Running /scripts/init-bottom ... done. | [ 1.484294] Not activating Mandatory Access Control as /sbin/tomoyo-init does not exist. | - runit: $Id: 25da3b86f7bed4038b8a039d2f8e8c9bbcf0822b $: booting. | - runit: enter stage: /etc/runit/1 | Starting hotplug events dispatcher: systemd-udevd. | Synthesizing the initial hotplug events (subsystems)...done. | Synthesizing the initial hotplug events (devices)...[ 1.687579] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 | done. | Waiting for /dev to be fully populated...[ 1.700596] sr 1:0:0:0: Attached scsi generic sg0 type 5 | [ 1.703218] ACPI: button: Power Button [PWRF] | [ 2.105448] RAPL PMU: API unit is 2^-32 Joules, 0 fixed counters, 10737418240 ms ovfl timer | [ 2.152185] cryptd: max_cpu_qlen set to 1000 | [ 2.348491] AVX2 version of gcm_enc/dec engaged. | [ 2.352216] AES CTR mode by8 optimization enabled | done. | Activating swap...done. | [ 3.116512] EXT4-fs (vda): re-mounted.

In particular, the user has no way to log into the system as no getty is being spawned. I see that the autopkgtest has to do this manually via "ln -s /etc/sv/getty-ttyS0 /etc/service/". Do you think there could be a better way to achieve this such that at least the console= kernel command line parameter is automatically issued a getty? Helmut
