RPM install fails on RHEL 5

[fommil]

I tried installing an RPM from this plugin and got this error

Creating system user: mdes in mdes with mdes user-daemon and shell /bin/false
useradd: unknown group mdes
Error in PREIN scriptlet in rpm package mdes-1.0.0_SNAPSHOT-1.noarch
error: %pre(mdes-1.0.0_SNAPSHOT-1.noarch) scriptlet failed, exit status 6
error:   install: %pre scriptlet failed (2), skipping mdes-1.0.0_SNAPSHOT-1
Installed products updated.

It looks like the mdes group is not being created before attempting to create the user mdes.

Actually I'm happy with root... but please tell me you don't try to delete the user/group on uninstall!

preinst-template has the correct order

[fommil]

Creating system group: mdes
groupadd: unrecognised option `--system'
Usage: groupadd [options] group

Options:
  -f, --force           force exit with success status if the specified
                group already exists
  -r,                       create system account
  -g, --gid GID         use GID for the new group
  -h, --help            display this help message and exit
  -K, --key KEY=VALUE       overrides /etc/login.defs defaults
  -o, --non-unique      allow create group with duplicate
                (non-unique) GID

this is on RHEL 5 so maybe the groupadd interface has changed?

[muuki88]

Wow, indeed. That is actually pretty nasty.

[fommil]

I'm guessing the --system flag did a bunch of useful stuff that you're relying on.

[muuki88]

AFAIK this only affects the UID range being used. Systemusers are defined in a different range. Besides that, nothing I know about.

[fommil]

ok, I'll try out tomorrow with --system removed and let you know. If you're looking at this in a docker of RHEL5 (or old fedora/arch) or something, that would be awesome please let me know.

I have tried working around this by creating overrides in src/debian/DEBIAN/control-functions and src/rpm/scriptlets/preinst-template but they are not being picked up. Am I using the correct directory and filename?

[fommil]

control-functions is a replacement, not a template, so after trying to work out the correct file to put into src/rpm the only workaround I could come up with was

    linuxScriptReplacements := {
      val orig = linuxScriptReplacements.value.toMap
      orig ++ Seq(
      // WORKAROUND https://github.com/sbt/sbt-native-packager/issues/621
      ("control-functions", orig("control-functions").replace(" --system", ""))
    )}.toSeq,

if I need to customise that control-functions value any further I'm going to have to have my own template and load it from disk at this point.

--no-create-home

also not supported on RHEL 5
