Try using the Shellvars_list module to parse /etc/default/grub, it supports splitting up a value into a number of nodes. $ augtool -A -t 'Shellvars_list incl /etc/default/grub' print /files/etc/default/grub/GRUB_CMDLINE_LINUX /files/etc/default/grub/GRUB_CMDLINE_LINUX /files/etc/default/grub/GRUB_CMDLINE_LINUX/quote = "\"" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[1] = "rd.md=0" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[2] = "rd.dm=0" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[3] = "rd.lvm.lv=vgcobalt/lvroot" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[4] = "$([" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[5] = "-x" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[6] = "/usr/sbin/rhcrashkernel-param" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[7] = "]" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[8] = "&&" /files/etc/default/grub/GRUB_CMDLINE_LINUX/value[9] = "/usr/sbin/rhcrashkernel-param" etc. -- Dominic Cleal Red Hat Engineering _______________________________________________ augeas-devel mailing list [email protected] https://www.redhat.com/mailman/listinfo/augeas-devel
