LTSP clients don't boot with a boot splash, all kernel logs are shown
during boot

Sincerely,
Serhii Horichenko

Hi Serhii,

please try to fix this. Set up a Debian Edu 12 tjener + workstation +
ltspserver and check if the problem still exists.

If it does, set up a Debian Edu 12 tjener + another machine with
Debian Edu 13 terminal server. Check if the problem still exists.

If it still exists, please look at the iPXE boot configuration in
/srv/tftp/. There you should be able to provide the keyword "splash"
to the boot prompt that is provided via PXE boot mechanism.

Once you know where to add "splash", investigate scripts in
debian-edu-config source package and check where best to provide some
code that inserts "splash" into the iPXE boot config.

Thanks!
Mike

Hi Mike,

FIX
it works only for Diskless Workstation (server's SquashFS image)
and doesn't work for Plain X2Go Thin Client modes
```
/srv/tftp/ltsp# diff ltsp-old.ipxe ltsp.ipxe
68c68
< set cmdline ${cmdline_method} ${cmdline_ltsp} ${cmdline_client}
---
```

I've tried to find where I could add 'splash' in debian-edu-config, but
didn't found.
Could it be that the file `ltsp.ipxe` is used as a template from the
ltsp.org project without any changes around the `cmdline`-variables?

Hi Serhii,

Ok, for diskless machines, this is also good already.

For X2Go thinclients, we maybe to have the package plymouth installed?
("splash" on the boot cmdline will not have an effect if the package
plymouth is missing).

Yes, the ltsp.ipxe is created by evoking the `ltsp ipxe` command.

However, in Debian Edu, we do some post-tweakings:
https://salsa.debian.org/debian-edu/debian-edu-config/-/blob/master/sbin/debian-edu-ltsp-ipxe?ref_type=heads

Please tinker with this script and let it modify the ltsp.ipxe file
that gets generated by ltsp's code.

Mike

Resolved in two MRs:
1. https://salsa.debian.org/debian-edu/debian-edu/-/merge_requests/4
2. https://salsa.debian.org/debian-edu/debian-edu-config/-/merge_requests/54

Can be closed.

Sincerely,
Serhii Horichenko

 .
   [ Daniel Teichmann ]
   * testsuite/ldap-server: Check /var/lib/ldap exists and is owned by
     openldap:openldap. Regression check for Debian bug #1144741.
   * debian/debian-edu-config.lintian-overrides: Fix stale reference. (Fixes
     commit: 63575146)
   * Drop unused wicd preconnect hook.
     wicd is no longer in Debian. The hook was the only remaining wicd
     integration and is not referenced anywhere else in the package.
   * testsuite/hostname: escape regex dot and exit non-zero on failure.
     The unescaped dot in the 'tjener.intern' grep matched any character.
     Escape it so the FQDN check is exact. Both error paths now exit 1 so a
     broken hostname fails the test instead of silently passing.
   * share/debian-edu-config/d-i/pre-pkgsel: resolve leftover merge conflict.
   * debian/control: Depend on iproute2
   * testsuite/network: Stop using net-tools, use ip from iproute2 instead
   * ldap-tools/ldap-debian-edu-install: Get MAC addresses via ip link instead
     of ifconfig
   * share/debian-edu-config/testsuite-lib.sh: Use ss instead of netstat
   * testsuite/ldap-server: Use ss instead of netstat
   * debian/control: Drop Depends: net-tools
   * share/debian-edu-config/d-i/pre-pkgsel: Tighten hostname= parsing and
     sanitization from /proc/cmdline.
     Handle hostname= as first cmdline token, ignore empty values and
     strip characters invalid in hostnames.
   * share/debian-edu-config/d-i/pre-pkgsel: strip hyphens only when present.
     Use 's/^-+//' / 's/-+$//' instead of '-*' so the substitution only
     fires when there actually is a leading/trailing hyphen to remove.
   * tools/create-debian-edu-certs: Switch root CA and server key generation
     to ECDSA prime256v1.
     RSA with 2048 bits is the bare minimum with OpenSSL 3. Replace
     'openssl genrsa' with 'openssl genpkey -algorithm EC' using the
     prime256v1 (secp256r1 / NIST P-256) curve.
   * tools/create-server-cert: Switch key generation to ECDSA prime256v1 and
     drop keyEncipherment key usage
     keyEncipherment is only meaningful for RSA keys. For ECDSA server
     certificates only the digitalSignature key usage is applicable
     (RFC 5480).
   * v3.cnf: Drop keyEncipherment from server cert key usage
     keyEncipherment is not applicable to ECDSA keys (RFC 5480), only
     digitalSignature is required for TLS server certificates.
 .

   * debian/control: Add to D: (debian-edu-config): procps. (Closes: #1136493).
   * ldap-tools/ldap-debian-edu-install: Make sure interactions with debconf
     are UTF-8 based.
     This resolves GECOS field transliteration after having retrieved
     debian-edu-config/first-user-fullname from the debconf db.
     (Closes: #939717).
   * share/debian-edu-config/d-i/pre-pkgsel: white-space cleanup
   * share/debian-edu-config/d-i/pre-pkgsel: Use 'tjener' in /etc/hostname
     and derive FQDN from /etc/hosts. (Closes: #893394).
   * testsuite/hostname: Test that /etc/hostname on installation profile
     Main-Server is set correctly
   * cf3/cf.cfengine3: Stop cfengine3 service on all Debian Edu machines.
     Esp. cf-execd (calling cf-agent command) clobbers the log on all Debian
     Edu clients (Debian Edu 12 and onwards) and thus on syslog.intern (aka
     tjener).
     In Debian Edu, we use cfengine3 for managing configuration adjustments
     via manual invocation of the cf-agent command, but we don't support
     (yet?) to use cfengine3 for constant system management.
     Partially addresses #1051834.
   * sbin/debian-edu-ltsp-install: Use KERNEL_PARAMETERS variable, if we
     define it
   * sbin/debian-edu-ltsp-install: Fix variable interpretation in sed commands
     ... by using double quotes, not single quotes.
   * sbin/update-hostname-from-ip: white-space cleanup
   * sbin/update-hostname-from-ip: Stop using net-tools, use ip command from
     iproute2 instead
   * share/debian-edu-config/d-i/pre-pkgsel: Support hostname override via
     /proc/cmdline. (Closes: #1008597).

   [ Wolfgang Schweer ]
   * share/debian-edu-config/d-i/pre-pkgsel: Cleanup pre-pkgsel from cruft.
     (Closes: #1055648).
 .
   [ Serhii Horichenko ]
   * ltsp: Add 'quiet splash' to hide boot details on clients.
     (Closes: #1065564).
   * etc/nagios3/debian-edu/commands.cfg: Add key -l for check_apt to list
     packages available for upgrade.
