The keyword davfs in /etc/fstab should not be displayed with colour red, it is a correct specified file system. In addition in a line like : //ehngsa.ibm.com /mnt/GSA cifs ... in /etc/fstab the dots in the hostname shouldn't displayed in red. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Ah, forgot to mention, that the keyword "askauth" in a line like : http://n22/davfs@n22/ /mnt/dav_n22 davfs noauto,user,askauth 0 0 should displayed in the same colour (green) as "noauto" and "user".
Fixed in 6.4.
