# this is a hack and without this cpufreq module is not working:
# when set_freqset_setuid is true and "e19_freqset" is set in setuidPrograms (this is taken care of in e19 NixOS module),
# then this postInstall does the folowing:
# 1. moves the "freqset" binary to "e19_freqset",
# 2. linkes "e19_freqset" to enlightenment/bin so that,
# 3. setuidPrograms detects it and makes appropriate stuff to /var/setuid-wrappers/e19_freqset,
# 4. and finaly, linkes /var/setuid-wrappers/e19_freqset to original destination where enlightenment wants it
