Re: svn commit: r305968 - head/etc/autofs
For MSDOS it's one thing and likely helps. But for ufs it doesn't
help. Soft updates already does an excellent job at reducing wear and
all async does is give added danger of dataloss. Linux distros don't
matter for UFS because different design decisions have been made for
ext[234] and UFS.

Re: svn commit: r305968 - head/etc/autofs
Mounting removable media async improves performance and reduces wear.
And AFAIK that's what most Linux distros used to do.

Re: svn commit: r305968 - head/etc/autofs
Hi,
Your commit message says in words exactly what the diff says in code.
Would you like to elaborate on why the change is made? I'm curious
because this could cause severe damage to the filesystem on unclean eject
of the media.
Regards,
Ronald.
