Nss libraries not found when using guix pack

[Jean-Christophe HAESSIG]

Hi,

I tried to deploy Slurm using guix pack :
guix pack -R -S /sbin=sbin -S /bin=bin slurm@19.05.8 nss-pam-ldapd sssd

User and authentication data comes from ldap (sssd). The libraries are 
present but the Slurm binary does not find them, and fails with an 
invalid user error.

-------------------

The library exists :
$ find /opt/ -iname 'libnss_sss.so*'
/opt/slurm/gnu/store/g9zf74246si96vhp47cyhkby89gj38py-sssd-1.16.5/lib/libnss_sss.so.2
/opt/slurm/gnu/store/nz0apgr4bxfmd77iijp8jn264c65z4s4-profile/lib/libnss_sss.so.2

------------------

but is not listed in 
/gnu/store/rkimbfkypl6gp6sjdjrv1lm1cn3q9xfa-slurm-19.05.8/etc/ld.so.cache

How can this be fixed properly ?

Thank you,
