Public bug reported:
"Recovery mode", whatever the linux kernel version chosen
freezes at early boot.
(x86-64, bare metal boot (not a virtual machine,
while there are containers handling on system too which might causes problem,
as a an upstream bug on systemd related to a virtual environment
entitles on "Failed to fork off sandboxing environment"
message like the one below)),
systemd 259.5-0ubuntu3 amd64
(some other packages versions and LSB, below after line "# packages / versions
/ LSB")
relevant kernel messages:
....
[ timestamp ] bpf-restrict-fs: BPF LSM hook not enabled in the kernel, BPF LSM
not supported # don't know if related...
[ timestamp ] coredump: 98((sd-gens)): |/bin/false pipe failed # /think
this is where starts/end the key problem, where I can't investigate myself
(binary, where exploring SYSTEM V was fine...)
[ timestamp ] systemd[1]: Failed to fork off sandboxing environment for
executing generators: Protocol errors
...
[ timestamp ] systemd[1]: Freezing execution
....
[ !!!!!! ] Failed to start up manager
....
[ timestamp ] clocksource: switched to clocksource tsc
(then complete freeze where even ctrl-alt-del don't work, only looong poweroff
button push - laptop)
# I suppose sd-gens is a function, anywhere in systemd process
# (systemd I currently can't figure out how it really works),
# function I'm unable to find anywhere I explored:
