The deploycfg carries the literal 'null', which went into the profile as
a password hash, so the installed root account reported a usable
password instead of a locked one. 15 substitutes '!' for this; the sed
delimiter has to move off '!' to carry it.
The default Etc/UTC is not in the tzdata list agama validates against,
so the load failed and the install fell through to agama defaults and
still reported completion. Normalize it and halt if the load fails.
prechroot.sh had setupssh.sh commented out and copied only the keys
inline, so nodes came up without shosts.equiv, without the CA in
ssh_known_hosts and without a setuid ssh-keysign.
Without it osdeploy import cannot generate a profile at all:
generate_stock_profiles opens profile.yaml unguarded, and initprofile.sh
seds the label into it. The label substitution also still looked for
'sle 15'.
While curl and agama download are happy with the CA bundle, zypper was not. Have pre.sh properly set up the CA certs.
Additionally, indicate the install subdirectory of the repository to agama via it's cmdline conf.
