Fixed In Version:	augeas-1.4.0-5.el7_5.1
Doc Type:	Bug Fix
Doc Text:	Previously, Augeas was not able to parse lines in the /etc/fstab file if they had white spaces at the beginning. This update fixes the Fstab lens of Augeas to correctly ignore white spaces at the beginning of lines. As a result, Augeas now reads /etc/fstab as expected.

Comment 3 YongkuiGuo 2018-03-29 06:34:52 EDT

Verified it with package:
augeas-1.4.0-5.el7_5.1.x86_64

Steps:
1. edit /etc/fstab and add whitespaces at the beginning of the following line:
  /dev/mapper/rhel_hp--dlxxx--04-home /home   xfs     defaults        0 0

2. run the augtool command:
augtool> print /files/etc/fstab
...
/files/etc/fstab/3
/files/etc/fstab/3/spec = "/dev/mapper/rhel_hp--dlxxx--04-home"
/files/etc/fstab/3/file = "/home"
/files/etc/fstab/3/vfstype = "xfs"
/files/etc/fstab/3/opt = "defaults"
/files/etc/fstab/3/dump = "0"
/files/etc/fstab/3/passno = "0"
...


So verified it.
