[augeas-devel] Changing arguments that already exist

[Ed]

It looks like I solved my own problem:

Here was the best situation I found (removing first and creating a new one):

rm /files/etc/pam.d/system-auth/*[module = 'pam_cracklib.so']/argument[.
=~regexp('lcredit=-.*')]
set /files/etc/pam.d/system-auth/*[module =
'pam_cracklib.so']/argument[last+1] lcredit=-$num

It can be done inline as well:

set /files/etc/pam.d/system-auth/*[module = 'pam_cracklib.so']/argument[.
=~regexp('lcredit=-.*')] lcredit=-$num
