portability: booth cannot build on Alpine

[fabbione]

@statzitz as in title, booth needs to be ported to Alpine

First, you need to make sure to use:

CONFIG_SHELL=/bin/bash ./configure ...

or the BOOTH_PKG_CHECK_VAR will generate a bad shell and turn into a syntax error during configure stage. Alpine default /bin/sh from busybox doesn´t support ${!varname} variable expansion.

Later booth will fail to configure:

[2026-03-19T05:14:54.682Z] checking for library containing sd_notify... no
[2026-03-19T05:14:54.682Z] configure: error: nametag provider required (libplumbgpl, or libsystemd when --without-glue)

At this point I am uncertain if I should try and install some systemd dependencies to make booth happy or someone needs to package libplumb*

First thing first: I can't acceed the CI since you migrated from jenkins to https://haci.fast.eng.rdu2.dc.redhat.com, I suppose this is a RedHad internal domain name? my DNS can't find an address for it.

@statzitz ops.. i copied the internal link instead of the external one..

Concerning the shell script, I think it is possible to replace ${!varname} by some eval for busybox's ash compatility, look at the following example: https://github.com/statzitz/pcs/blob/225e9dbc26b8d0a1f48c23fd42209a0d46924a38/configure.ac#L78-L92

It should be something really similar I think

sure, if you have time to prep a PR? pcs is building fine, so i guess a similar will fix will do.

We are missing only few components to build on Alpine and we are pretty much done.

Alright, I will do it (the PR) when I have time.

I can't investigate/experiment right now about libplumbgpl or libsystemd, I will try to find some time this week

It´s no rush my side. I am happy to have Alpine in CI and that almost everything is fixed or being fixed. We should have a full HA stack for you to package pretty soon.
