IMHO setup for reboot has been usually handled outside of LTP (in frameworks
which use LTP), because without any more capable runner [*] reboot would just
stop testing. I'm not saying it's not possible, but requires more thinking. At
least I'd add some variable which would prevent boot (and thus tst_brk TCONF
would be issued for this test).

I wonder what other think about it.

Kind regards,
Petr

[*] runltp is dead, but even Cyril's not yet upstreamed runltp-ng [1] and other
plans [2] does not handle reboot either. It'd have to be some service which can
pick-up the state.
