Le problème apparaît avec gawk, libnss_compat et libnss_files car j’ai constaté que sur RHEL 3, RHEL 4, RHEL 6 (et sûrement RHEL 5), gawk et un ensemble de libnss sous /usr/lib sont des liens sur ../../xxxxxx.

Mes tests RHEL 4

# /bin/tar --version
tar (GNU tar) 1.14

# whereis gawk | xargs ls -l

# echo "/usr/test/../bin/gawk" | perl -pi -e 's|([^/]+)/([^/]+)/\.\./([^/]+)|$1/$3|'
/usr/bin/gawk       (ne fonctionne que dans ce cas de test hypothétique)
