First, let me prefix my inline responses with stating that: Due to the addition of the "failok" mount(8) option, it is highly likely th= at this may solve our problems. However, since the "failok" addition is currently not available in any -REL= EASE, we cannot test it for production deployment (maybe in 6-months). With that being said, we look forward to when FreeBSD 8.3-RELEASE will be m= ade available (as I've confirmed that "failok" is tagged for RELENG_8, the = source for what should be 8.3 when created).

I've been thinking about it and the patch does have the following two negat= ives: 1. disabling mountlate means the administrator needs to memorize that whils= t looking at fstab(5) that "late" filesystems could be neutered (good or ba= d, requires modification of man-pages, re-training to learn new axioms, etc= .) 2. mountlate is metaphorically the "enforcer" of mountcritremote. Disabling= mountlate means mountcritremote doesn't really make remote mounts critical. So, up until this point, we'd not been aware of the new "failok" option (wh= y would we? it's not really available yet) and now that we know about it, w= e look forward to checking it out in a future release. But at this time, ne= ither 8.1 nor 8.2 support it. Until we can upgrade, we'll have to resort to= modifying the system in some way. > I think Jilles had a good point, it's likely that the best actual change > to be made here is better documentation of the failok knob for fstab. >=20 Gcooper raised docs/163742 to address the lacking documentation. --=20 Devin _____________ The information contained in this message is proprietary and/or confidentia= l.
